Aquarium Maintenance Service

The shortcut: Residential is the side hustle. Commercial accounts — dental offices, restaurants, hotel lobbies — are the real money. One commercial contract at $400/month beats five residentials at $80, and the dentist never watches over your shoulder while you work.

Industry: Pet Services | Investment level: Small — $3,000-$8,000 | Time to launch: 6-10 weeks (LLC + insurance + first 5 accounts) Best for: People who already keep a tank at home, can troubleshoot a protein skimmer at 11pm without panicking, and would rather drive a maintenance route than work a fish-store retail counter. What you'll likely make: $1,500-$2,500 month 3, $3,500-$5,000 month 6, $6,000-$9,000 month 12. Math is in Section 4.

Market Opportunity

Walk into a dentist's waiting room, a corporate office lobby, or a mid-range hotel check-in area and there's a reasonable chance you'll find a fish tank. There's also a reasonable chance the back glass is coated in brown algae, the water line is four inches low, and one fish is floating sideways near the filter intake. Nobody on staff knows what to do about it. The dentist bought the tank because a sales rep told him it would calm anxious patients — and it would, if it looked anything like it did on install day. The office manager isn't going to learn the nitrogen cycle. They just want someone who shows up, fixes it, and sends a monthly invoice they never have to think about again.

The U.S. aquarium services market is small and fragmented — a long tail of one-person providers plus a few regional firms like Aquatic Interiors and Living Art Aquatic Design holding the bigger commercial accounts. The IBISWorld pet services category runs around $13B in annual revenue, and aquarium maintenance is a sliver inside that — most metros have fewer than five real service providers covering thousands of tanks.

The trap new providers fall into is chasing residential hobbyists because that's the world they came from. Residentials are price-sensitive, cancel when summer travel hits, and half want to do their own maintenance. Commercial is the opposite — the dental office signs a 12-month contract, pays the invoice without reading it, and refers you to every other practice in the building because nobody there wants to think about the tank either.

Launch With AI

Pro section. Aquarium maintenance is a commercial-route + reef-husbandry-track-record business — AI doesn't drag a Python hose through a dental office, troubleshoot a protein skimmer at 11pm, or read a refractometer through fogged-up safety glasses. But the time you waste hand-typing the dental-office cold-walk script for the Tuesday 10am-2pm walk-in window, drafting the commercial water-damage liability cap clause, and writing the post-visit photo report is exactly the time you should spend on one more in-person dental-office walkthrough. AI does the writing tail. You do the hands.

The trap most first-year aquarium operators fall into: they paste their service description into ChatGPT and ship "we maintain home aquariums for $50/month." AI confidently writes residential-hobbyist marketing — but residentials are price-sensitive, cancel during summer travel, and half want to do their own maintenance. Commercial accounts pay 30-50% more, never cancel, refer you to the building, and the dentist never watches over your shoulder. AI is for the writing tail (commercial cold-walk, water-damage liability cap, equipment upsell email, Reef2Reef intro, post-visit photo report). Every salinity decision, every alkalinity-crash judgment, every "I won't take this SPS reef contract yet" call is yours.

Important up-front: AI cannot dose a reef tank, judge whether a coral frag is healthy, or have the conversation with the dentist about why $200 of marked-up frags is the right price. It will also confidently miss the OSHA Hazcom 29 CFR 1910.1200 SDS-binder trap (your vehicle needs one), the CITES Appendix II trap on wild-caught coral imports (federal violation if unpermitted), and the sales-tax-on-equipment-resale trap (the maintenance visit may be exempt but the protein skimmer markup is taxable). You own every salinity reading, every reef decision, every contract clause; AI scales the writing around them.

The Workflow

Commercial cold-walk script + Tuesday 10am-2pm walk-in batch (ChatGPT + Canva, ~30 min one-time setup). Commercial = your real money. Paste:

"I'm an aquarium maintenance operator in [city] with $1M GL with explicit water-damage coverage, RO/DI system, refractometer + API kit + Tramex moisture meter, and BRS Pro wholesale account. I want 8-12 active commercial accounts by month 3 by cold-walking dental offices + medical practices + restaurants + hotel lobbies + corporate offices in the Tue/Wed 10am-2pm window. Build me the package: (a) the targeting — 1 commercial corridor of 30-50 visible-tank offices in 1 sq mile, prioritize dental practices (highest neglect rate) + medical specialties + boutique hotels (lobby tanks) + casual restaurants (waiting-area tanks), (b) the in-person walk-in pitch I deliver Tue/Wed 10am-2pm with a small before/after photo book: 'hi, I'm [name] from [my brand], local aquarium maintenance. Noticed your tank — saw [specific observation: brown algae on back glass / water line low / one fish floating]. I do monthly visits at $150-$300 covering water change + glass clean + parameter check + livestock health + a written photo report. $1M GL with water-damage coverage so your office stays dry. Want me to leave my one-pager + show you what your tank could look like in 30 days?,' (c) the leave-behind 1-pager (Canva: 5 commercial before/after photos with property names + dates, $1M GL with water-damage coverage line, my MASNA-affiliated reef-club listing or Reef2Reef profile, sample monthly photo report, $150-$300 monthly contract pricing, my Calendly), (d) the 5-day phone follow-up to the office manager ('hi [first name], dropped by Tuesday — want me to do the free 30-day trial visit this Thursday? Show you what consistent maintenance looks like. No pressure'), (e) the post-walkthrough quote text ('hi [first name], walkthrough done — your tank is [size + livestock]. Monthly visit $[X] covers everything. First visit free as the trial, recurring auto-bill via Jobber starting visit 2. Reply Y to schedule for [date]'), (f) the absolute don'ts: NEVER quote per-tank below $90 commercial (you bleed margin), NEVER skip the water-damage coverage mention (the office manager's #1 question), NEVER chase residential at the same price (cancellations + complaints kill your route). Tone: confident pro + commercial-property-fluent. Output paste-ready cold-walk script + 1-pager."

30-50 walk-ins/week. Convert ~1 in 8 to walkthrough, ~1 in 3 walkthroughs to monthly. Hit 8-12 accounts by month 3 = $1.5-3K/month route base.
Commercial water-damage liability cap clause + service agreement (ChatGPT + attorney review, ~30 min one-time setup). Career-saving clause. Paste:

"I'm an aquarium maintenance operator. The single most important contract clause for commercial accounts is the consequential-damage liability cap — a flooded dental office can run $2K-$10K cleanup + business-interruption claims that wipe me out. Build me the per-commercial-account service agreement template (then I'll send to a local attorney for $300 review): (a) the parties — my LLC + commercial client + property address, (b) the scope — monthly visit covering water change [X gallons], glass cleaning, equipment check, parameter testing (pH, salinity, ammonia, nitrite, nitrate, alkalinity for reef), livestock health observation, written photo report within 24 hours, (c) the per-month service fee + auto-bill via Jobber + Net-15 invoicing, (d) the consequential-damage liability cap clause — 'In the event of equipment failure, hose burst, or other unforeseen incident causing water damage, [my brand]'s liability is limited to the cost of replacement of damaged equipment + reasonable cleanup costs incurred within 24 hours of incident, NOT to exceed [$X cap aligned with my GL water-damage limit]. [My brand] is not liable for consequential damages including business interruption, loss of revenue, or claims by third parties beyond the equipment + cleanup limit,' (e) the per-visit photo + parameter log requirement (your IICRC-equivalent CYA), (f) the termination clause (30-day written notice either party), (g) the absolute don'ts: NEVER skip the consequential-damage cap (one $50K business-interruption claim ends your business), NEVER under-cap below your GL water-damage limit (uninsured exposure), NEVER take a commercial reef contract without 12+ months of personal SPS reef stability (a coral crash = $5K-$10K livestock-replacement claim). Tone: confident pro + contract-fluent. Output paste-ready service agreement for attorney review."

One liability cap clause = your $50K-saving career insurance.
Reef2Reef + MASNA reef-club intro + reference-tank post (ChatGPT + Canva, ~20 min one-time setup). Reef2Reef = highest-LTV residential commercial buyers. Paste:

"I'm an aquarium maintenance operator in [city]. Build me the Reef2Reef + MASNA-club outreach: (a) the Reef2Reef sub-forum post in my regional sub-forum after building 30+ post karma — 'hi r/[my city] reef community, [my brand] aquarium maintenance offering monthly + emergency reef service in [city + 25 mi radius]. Reference tank: 75-gal mixed reef, 18 months stable, [list livestock + dosing setup], BRS Pro account for clients. Photos attached. Pricing $150-$300/month commercial, $100-$200/month residential reef. $1M GL with water-damage coverage. Vet referrals welcomed. DM if your sitter circle doesn't cover reef,' (b) the per-photo upload — wide shot of my reference tank + 3 close-ups of livestock + my parameter log + my BRS Pro membership badge, (c) the MASNA-affiliated reef-club monthly meeting — show up consistently, bring a coral frag I propagated for the swap, mention I'm taking on commercial accounts in conversation but never lead with the pitch, (d) the per-club referral DM template ('hi [first name], you mentioned your tank at the meeting Tuesday — happy to do a free assessment visit. Reply Y if helpful'), (e) the absolute don'ts: NEVER post in Reef2Reef without 30+ post karma first (kills your reach), NEVER post without my reference-tank photos (the entire credibility test), NEVER take a reef contract before my own SPS reef has been stable 12+ months (livestock-replacement claim). Tone: warm pro + reef-keeper community member. Output paste-ready Reef2Reef post + per-club DM template."

Reef2Reef post = 2-5 inbound inquiries/month + 1-2 commercial leads from reef-enthusiast business owners (highest LTV).
Equipment upsell + BRS Pro markup email (ChatGPT, ~20 min one-time setup). Equipment markup = your hidden margin engine. Paste:

"I'm an aquarium maintenance operator with BRS Pro wholesale account (10-15% below retail). Build me the per-account equipment upsell email I send 2-3x/year: (a) the per-quarter system-audit text ('hi [first name], this month's visit notes — your protein skimmer is undersized for the bioload + your LED fixture is 4 years old (PAR drops ~30% by year 5). Want me to spec the next upgrade? Wholesale BRS Pro pricing + I install on next visit at no extra labor cost'), (b) the per-upgrade email template ('hi [first name], here's the spec: replace your skimmer with [specific BRS Pro brand + model] — list price $400, my wholesale $340, your price $400 (markup goes to my install + warranty support). LED fixture replacement [brand + model] — list $300, my wholesale $255, your price $300. Total $700 + I install on Wednesday's visit. Reply Y to add to invoice'), (c) the per-equipment markup rule (cost x 1.3-1.4 = retail), (d) the per-quarter sales-tax remit reminder (equipment resale = tangible personal property = taxable in nearly every state — register state sales-tax permit before first equipment upsell), (e) the per-installed-equipment 30-day check-in text ('hi [first name], 30 days on the new skimmer — bioload looks great in this morning's photos. Working as expected? Any questions?'), (f) the absolute don'ts: NEVER mark up above 50% (community talks + Reef2Reef kills you), NEVER skip sales tax on equipment (back-tax + 25-50% penalty when accountant flags), NEVER install used equipment from another customer (warranty + liability). Tone: confident pro + reef-fluent. Output paste-ready quarterly upsell email + 30-day check-in."

One commercial reef account with 2 equipment upgrades/year × $200 markup avg = $400/account/year of pure margin on top of monthly fees.
MileIQ + Jobber route clustering automation (Jobber + ChatGPT, ~15 min one-time setup). Mileage = your tax shield. Paste:

"I'm an aquarium maintenance operator with [N] active accounts on Jobber. Build me the route + mileage automation: (a) the per-week route plan — cluster Monday accounts in 1 zip code + Tuesday in another + Wed-Fri progressively, never cross-town in same day, (b) the MileIQ deductible reminder (40 mi/day × 220 working days × $0.67 IRS standard mileage rate = $5,896/year deductible — only if logged, MileIQ does it automatic), (c) the per-customer photo + parameter Jobber template — water change gallons, livestock observed, parameter readings (pH/salinity/ammonia/nitrite/nitrate/alkalinity), equipment check, recommendation, before/after photo, (d) the per-quarter customer-renewal nudge text ('hi [first name], 3-month service review for [tank size] — bioload stable, parameters in range, recommend [specific upsell] for next quarter. Want me to add to next visit?'), (e) the per-cancellation save script ('hi [first name], received your cancellation request — happy to pause for 60 days if you're traveling, or downgrade to bi-monthly visits at $X if cost is the issue. Want to chat before I cancel?'), (f) the absolute don'ts: NEVER skip the per-visit photo + parameter log (your service agreement requires it + your save-the-account ammo), NEVER cross zip codes in one day (kills your hourly), NEVER skip MileIQ ($5,896/yr deductible on the table). Tone: warm pro + reef-fluent. Output paste-ready Jobber automation + cancellation save script."

Route clustering + MileIQ + per-visit log = 30% more time on actual work + $5,896/yr tax shield.

Time Saved Per Week

Roughly 3-4 hours/week once your commercial cold-walk + service agreement + Reef2Reef intro are built:

Commercial cold-walk + Tuesday batch: 1-time setup → reused per cold-walk day
Water-damage liability cap service agreement: 1-time setup → reused per commercial sign
Reef2Reef + MASNA outreach: 1-time setup → reused per club meeting
Equipment upsell + BRS Pro markup: 1-time setup → reused per quarterly review
MileIQ + Jobber route automation: 1-time setup → fires automatically

Trade that time for: 5 more dental-office cold walks per week, attendance at the next MASNA club meeting, and the next MACNA conference (if budget allows — best networking event in the niche).

Total AI Stack Cost

Budget tier ($35/mo): Jobber Core ($29) + MileIQ ($6) + ChatGPT free + Canva free + Google Business Profile.
Full tier ($55/mo): Add ChatGPT Plus ($20). Worth it the day you sign commercial account #5 — service agreement quality + equipment upsell email jump materially with GPT-4.
Compare: A part-time office manager for cold-walk follow-ups + equipment upsell + cancellation saves runs $400-$700/month. Full AI stack is one-tenth that cost.

Cancel anything you don't open in a 7-day window. Skip Instagram + TikTok ads — Reef2Reef + commercial cold-walks out-convert any social channel for 18+ months.

Your First Win

30 minutes from now your commercial cold-walk script is laminated + your first commercial corridor is mapped — you're walking 30-50 dental + medical + boutique-hotel offices Tuesday + Wednesday 10am-2pm. Open ChatGPT (free tier works). Paste:

"I'm an aquarium maintenance operator in [my city] with: $1M GL with explicit water-damage coverage (confirmed in writing with broker), RO/DI system, refractometer + API freshwater + saltwater test kits + Tramex moisture meter, BRS Pro wholesale account, MileIQ on phone, MASNA-affiliated local reef club membership. The single biggest leverage in this trade is the Tue/Wed 10am-2pm commercial corridor cold-walk — every commercial account = $150-$300/month + 30-50% above residential pricing + 12-month no-cancellation + refers me to every other practice in the building. Build me the 1-page laminated commercial cold-walk script + the first-corridor map: (a) the targeting — pick 1 commercial corridor of 30-50 visible-tank offices in 1 sq mile within 12 minutes of my home base, prioritize dental practices (highest neglect rate) + medical specialties + boutique hotel lobbies + casual-dining restaurants with waiting-area tanks, (b) the in-person walk-in pitch I deliver Tue/Wed 10am-2pm with a small before/after photo book — 'hi, I'm [name] from [my brand], local aquarium maintenance. Noticed your tank — saw [specific observation: brown algae on back glass / water line low / one fish floating]. I do monthly visits at $150-$300 covering water change + glass clean + parameter check + livestock health + a written photo report. $1M GL with water-damage coverage so your office stays dry. Want me to leave my one-pager + show you what your tank could look like in 30 days?,' (c) the 1-page leave-behind (5 commercial before/after photos with property names + dates, $1M GL with water-damage coverage line, MASNA-affiliated reef-club listing or Reef2Reef profile link, sample monthly photo report, $150-$300 monthly contract pricing, my Calendly), (d) the 5-day phone follow-up — 'hi [first name], dropped by Tuesday — want me to do the free 30-day trial visit this Thursday? Show you what consistent maintenance looks like. No pressure', (e) the post-walkthrough quote text — 'hi [first name], walkthrough done — your tank is [size + livestock]. Monthly visit $[X] covers everything. First visit free as the trial, recurring auto-bill via Jobber starting visit 2. Reply Y to schedule for [date]', (f) the absolute don'ts: NEVER quote per-tank below $90 commercial (you bleed margin), NEVER skip the water-damage coverage mention (the office manager's #1 question), NEVER take a reef contract before my own SPS reef has been stable 12+ months (livestock-replacement claim risk), NEVER skip the consequential-damage liability cap in the service agreement (one $50K business-interruption claim ends my business), NEVER skip sales tax on equipment resale (taxable in nearly every state). Tone: confident pro + commercial-property-fluent + reef-disciplined. Output paste-ready as a 1-page laminated cold-walk script + a Tuesday + Wednesday 10am-2pm route map for 30-50 commercial offices within 12 minutes of [my home base zip]."

Print + laminate it Sunday. Walk 30-50 offices Tuesday + Wednesday 10am-2pm. 4-6 walkthroughs scheduled = 2-3 monthly contracts signed = $300-$900/month of recurring revenue from one Tuesday.

Product / Service Offering

You're selling four things, in this order of importance:

Monthly maintenance contracts — the core product. A scheduled visit covering water change, glass cleaning, equipment check, parameter testing, and livestock health. About 70% of your revenue at month 12 should sit here.
New tank setup and cycling — $300-$800 to set up a client-owned tank, $1,500-$10,000 for a full design-build-cycle install. The high-ticket event that almost always converts into the maintenance contract.
Equipment sales and upgrades — protein skimmers, return pumps, LED fixtures, RO/DI systems. Buy at BRS (Bulk Reef Supply) Pro account pricing (10-15% below retail), resell at retail. Small margin per item; it adds up across a route.
Emergency call-outs — heater stuck on at 2am, return pump failed Friday before a holiday. $100-$200 per visit on top of the monthly contract.

The kit fits in a sedan: buckets, Python hose, magnetic scrapers, refractometer, API freshwater and saltwater test kits, replacement media, Tropic Marin salt for reef accounts, ATM Colony bottled bacteria for new-tank cycling, and a labeled chemical bin. Skip copper-based algaecides in month one — they're regulated as pesticides in some states.

Revenue Model

Unit economics for a solo provider working a mixed route out of a personal vehicle:

Service	Price	Variable cost (water, salt, supplies, fuel)	Time (incl. drive)	Take-home per visit
Residential freshwater (monthly visit, up to 55 gal)	$50-$100/mo	$8-$15	60 min	$40-$85
Residential saltwater/reef (monthly, up to 75 gal)	$100-$200/mo	$20-$40	90 min	$80-$160
Commercial freshwater (lobby/office, monthly)	$100-$200/mo	$10-$20	60 min	$90-$180
Commercial saltwater/reef (restaurant/hotel, monthly)	$200-$500/mo	$25-$60	90-120 min	$175-$440
Equipment resale markup (skimmer, LED, pump)	20-35% over BRS Pro	shipping	n/a	$40-$300 per item

Your first $1,500 month = 4 residential freshwater × $80 + 3 commercial freshwater × $150 + one tank setup project at $400 = $1,170 + $400 = $1,570.

Your first $4,500 month = 6 residential reef × $150 + 8 commercial averaging $300 = $3,300, plus two equipment upsells (a $400 protein skimmer at 30% markup, an LED fixture at $200 markup) = roughly $3,740. Add one new-tank install at $1,500 and you're at $5,240. The equipment-sale math is what new providers under-count: a single commercial reef account that lets you spec the next return pump or LED upgrade is $200-$500 in pure markup on top of the monthly fee, twice a year.

The IRS 2024 standard mileage rate is $0.67/mile. At 40 miles a day across 220 working days, that's $5,896 in deductible mileage — money you keep at tax time only if you logged it. Use MileIQ ($5.99/month) from week one.

Startup Costs

LLC + EIN + business checking: $35-$500 LLC filing by state (LLC University 50-state table). Free EIN at IRS EIN Online — never pay a third party.
GL insurance with water-damage coverage: $500-$900/year via Insureon. Confirm the water-damage limit in writing — see Section 5.
Service kit: $800-$1,500. Python hose, 5-gallon buckets, magnetic scrapers, refractometer, API test kits, digital pH/TDS meters, chemical bin with dechlorinator and two-part, replacement media, and a labeled SDS binder.
RO/DI water system: $200-$400 from BRS. You can't service reef tanks with tap water.
Vehicle outfitting: $400-$1,500. Tubs, a 12V transfer pump, a folding cart. A Subaru Outback or minivan handles a 15-account route — no van required in year one.
Software: Jobber at $49-$129/month for routing, invoicing, and SMS reminders. Worth it once you cross 8 accounts.
First 60 days of inventory: $400-$800 in salt, dechlorinator, replacement media, and supplements you'll resell at markup.

Realistic all-in: $3,000 if you already own a vehicle and a cycled reference tank at home; $8,000 from zero on insurance, RO/DI, kit, and vehicle outfitting.

Legal & Formation

Business entity. Single-member LLC the day you sign your first commercial contract. A burst hose in a dental office can produce a $5,000-$20,000 water-damage claim; a reef crash can produce a livestock-replacement claim in the same range. Without an LLC, those land on your personal assets. Get your EIN free at IRS — never pay a third party. S-corp election is worth running the math on once net profit clears roughly $80K/year, typically year two or three on a solid commercial route.

Licenses & credentials. No state license is required to maintain aquariums in most states. What you do need: a Pet Tech PetSaver or American Red Cross pet first aid card ($30-$75) for homes with pets, a Checkr background check ($25-$50) to show nervous residential prospects, and a state pesticide applicator license if you'll apply copper-based algaecides commercially. There's no certifying body the way NDGAA (National Dog Groomers Association of America) covers grooming. The credibility signals reef clients look for are membership in MASNA (Marine Aquarium Societies of North America), an active Reef2Reef profile with photos of your reference tank, and attendance at MACNA (Marine Aquarium Conference of North America).

Industry-specific risk. Three traps end this business and they hit in this exact order. First, chemical SDS handling and Hazmat transport. Aquarium maintenance involves regulated chemicals — dechlorinators, copper-based algaecides (pesticides in some states), ammonia removers, reef additives. Maintain Safety Data Sheets for every chemical you transport under OSHA's Hazard Communication Standard (29 CFR 1910.1200), and note that certain salts and medications require Hazmat shipping classifications in commercial quantities. Keep a labeled SDS binder in your vehicle from day one. Second, CITES (Convention on International Trade in Endangered Species) for coral and livestock imports. Wild-caught reef corals and many invertebrates require Appendix II permits via USFWS. Selling or transporting unpermitted CITES coral is a federal violation. Source aquacultured frags from BRS or a local reef club in year one and stay out of import paperwork entirely. Third, sales tax on tangible goods. The maintenance visit is generally exempt in most states, but livestock, equipment, chemicals, and supplements you resell are tangible personal property and almost always taxable. Register for the permit before your first equipment upsell.

One contract clause sits inside this section: water-damage liability cap. Your GL policy may sublimit water damage, and a flooded dental office can run $2,000-$10,000 in cleanup before the carpet is pulled up. Get the broker's water-damage limit in writing, then cap your consequential-damage liability in every commercial contract at equipment replacement value — not the client's lost business. This is the single most important clause in your contract.

Marketing & First Customers

Your first 10 accounts almost never come from Google ads. Three channels, in this order:

Cold-walking commercial buildings with visible tanks. Highest-ROI channel in this business. Walk a strip of medical offices, dental practices, restaurants, and hotel lobbies in your target zip codes. Bring a small before/after photo book. The pitch is one sentence: "I noticed your tank — I'd love to show you what it could look like with monthly service." Conversion on a visibly neglected tank: 15-25%. Plan on 30-50 cold walks per week in month one to land 4-6 commercial accounts in the first 60 days.
Reef2Reef forum and local reef club presence. Reef2Reef has 200,000+ members and a regional sub-forum for nearly every U.S. metro. Post in your local thread with photos of your reference tank. Expect 2-5 inbound inquiries per active month from hobbyists, plus 1-2 from business owners who are reef enthusiasts themselves — the highest-LTV commercial accounts you'll land all year. MASNA-affiliated reef clubs meet monthly and become a referral pipeline if you show up consistently.
MACNA and regional aquarium trade events. The annual conference is where established firms recruit and meet wholesale livestock vendors. A first-year solo provider who works the floor typically lands 1-2 commercial leads from facility-manager attendees and 3-5 supplier relationships. Badge runs $200-$400.

Skip Instagram and TikTok in year one. A Reef2Reef profile and a Google Business Profile with five real reviews out-converts any social channel for the first 18 months.

First 90 Days

Week 1. File LLC. Get EIN free at IRS. Open business checking. Buy domain.
Week 1-2. Bind GL policy with explicit water-damage coverage in writing. Get pet first aid cert and run a background check on yourself.

Week 10-12. Hit 8-12 active monthly accounts plus one new-tank install in the books. Target: $3,000-$4,500 month, route clustered inside 2-3 zip codes.

Common Pitfalls

Taking a reef contract before you've kept your own reef tank stable for a year. A reef with SPS corals, dosing systems, and $3,000 in livestock is not a freshwater goldfish tank. A failed reef from an alkalinity crash or pest introduction means $2,000-$10,000 in livestock replacement plus the client's tank decommissioning. Start with freshwater and FOWLR (fish-only with live rock). Don't accept SPS reef contracts until you've grown SPS yourself for 12+ months.
No water-damage liability cap in the commercial service contract. One failed hose fitting during a service visit can flood a dental office with 20 gallons and produce a $2,000-$10,000 cleanup bill plus business-interruption claims. Without a clause capping consequential-damage liability at equipment replacement value, you're personally exposed to the full damage. The clause costs nothing and saves your business in year three.
Underpricing commercial accounts by treating them like residentials. Commercial accounts are 12 months no-cancellation, pay on time, and refer you to every other practice in the building — worth 3-4x the lifetime value of residentials at the same price point. Price commercial 30-50% above residential per gallon. The dentist isn't comparing your rate to a hobbyist's; she's comparing it to "not having to think about the tank."
Not collecting sales tax on equipment and livestock resale. The maintenance visit is exempt in most states, but the protein skimmer you marked up 30% and the $200 in coral frags you sold are taxable goods. Skip the permit and you're personally on the hook for back-tax plus penalties — often 25-50% of the uncollected amount — when an accountant flags an invoice years later. Register the permit in week one. One form, $0 in most states.
