Aquarium Maintenance Cost in Singapore: Monthly Breakdown

Before committing to an aquarium, smart hobbyists ask: what will it actually cost to run each month? This aquarium maintenance cost Singapore breakdown from Gensou Aquascaping at 5 Everton Park — with over 20 years of hands-on experience — lays out real numbers for electricity, consumables, and professional services so you can budget with confidence. Understanding aquarium maintenance cost upfront prevents unpleasant surprises down the road.

Electricity: The Biggest Ongoing Expense

Lighting, filtration, and heating or cooling are always running. A typical 90 cm planted freshwater tank with an LED light (8 hours daily), canister filter (24/7), and no chiller draws roughly 50–80 watts on average. At Singapore’s current electricity tariff of approximately $0.33 per kWh, that translates to around $12–$20 per month.

Add a chiller for cool-water species and the figure jumps significantly. A 1/10 HP chiller running four to six hours daily in a non-airconditioned room can add $25–$50 monthly. Marine tanks with protein skimmers, wave makers, and powerful lighting push electricity costs to $30–$60 or more for a 120 cm reef setup.

Water Conditioner and Test Kits

A bottle of Seachem Prime (500 ml, around $18–$22 on Shopee) treats roughly 5,000 litres — enough for months of weekly water changes on a standard tank. Liquid test kits like the API Master Kit ($35–$45) last 200+ tests. Combined, budget about $5–$8 per month for these essentials when amortised over their lifespan.

Fertilisers for planted tanks add another $5–$10 monthly, depending on dosing regimen. All-in-one liquids like APT Complete simplify the routine and keep costs predictable.

Filter Media and Replacement Parts

Mechanical filter pads need rinsing fortnightly and replacing every two to three months ($3–$8 per pack). Biological media like ceramic rings or sintered glass lasts years and rarely needs replacement. Carbon, if used, should be swapped monthly ($5–$10). Canister filter O-rings and impellers are infrequent expenses — perhaps $10–$20 annually.

For a typical freshwater setup, filter consumables average roughly $5–$10 per month.

Fish Food

Quality flake, pellet, and frozen foods are not expensive per serving. A tub of high-quality micro pellets ($8–$15) lasts a small community tank two to three months. Frozen bloodworms and brine shrimp ($2–$4 per blister pack) supplement the diet once or twice weekly. Monthly food cost for a standard community tank: approximately $5–$10.

Water: Less Than You Think

Singapore’s PUB water tariff is among the world’s most transparent. A 25 % weekly water change on a 200-litre tank uses roughly 200 litres per month. At current rates (around $2.74 per cubic metre including all surcharges), that costs under $1 per month. Water is genuinely the cheapest part of the hobby.

Professional Maintenance Services

DIY hobbyists save on labour but invest time. If you prefer hands-off ownership — common for office and restaurant installations — professional maintenance services in Singapore range from $80–$200 per visit for freshwater tanks and $150–$400 for marine, depending on tank size and frequency. Most providers offer fortnightly or monthly packages.

At Gensou Aquascaping, our maintenance contracts cover water changes, glass cleaning, plant trimming, livestock health checks, and emergency call-outs — bundled into a predictable monthly fee.

Monthly Cost Summary

For a self-maintained 90 cm freshwater planted tank in Singapore, expect roughly $30–$50 per month all-in (electricity, consumables, food, water). A 120 cm marine tank runs $60–$120 self-maintained, or $200–$500 with professional servicing. These figures exclude livestock replacement and one-off equipment upgrades, which are intermittent rather than monthly.

Budgeting realistically for aquarium maintenance cost in Singapore lets you enjoy the hobby without financial stress. The initial investment grabs attention, but it is the steady monthly outlay that determines whether an aquarium remains a joy or becomes a burden.
