Aquarium Calculator API
Aquarium maths as an API, computed locally and deterministically. The volume endpoint computes a tank's water volume — in US and UK gallons and litres — for a rectangular, cube, cylinder, hexagonal or bow-front tank from its dimensions (inches by default, or centimetres, millimetres and metres), and applies a fill factor (default 0.9) for substrate, decoration and freeboard to give a realistic net volume. The stocking endpoint gives a rough stocking load from the tank volume and the total length of fish using the classic inch-per-gallon guideline, reporting the maximum recommended inches and how heavily stocked the tank is. The waterchange endpoint computes the water-change volume for a percentage, with an optional dechlorinator dose. Everything is computed locally and deterministically, so it is instant and private. Stocking is a rough beginner guideline only — real stocking depends on the species, filtration and bioload. Ideal for aquarium and fishkeeping apps, pet-shop and hobbyist tools, and tank-setup planners. Pure local computation — no key, no third-party service, instant. Live, nothing stored. 3 endpoints. This is aquarium maths; for swimming-pool volume and chemical dosing use a pool API and for storage-tank gauging use a tank API.
