About FishTankCalculators.com

What this site provides

FishTankCalculators.com provides free aquarium planning calculators for volume, fish tank size, stocking, heater size, and filter flow.

How the calculators work

The tools use user-provided dimensions, gallons or liters, temperature inputs, documented fish data, and clearly stated calculation models. The assumptions are documented in the methodology.

Fish data architecture

Fish data is synchronized at build time, normalized into local data, and embedded into published calculator pages. Visitors do not send calculator inputs to the external fish-data API.
