Editorial Team

Fish Tank Volume Calculator is built and maintained by a small team of fishkeeping enthusiasts and web developers who wanted a calculator that was accurate, fast and genuinely easy to use.

Our experience

Between us we have kept freshwater community tanks, planted aquascapes and larger display tanks, so we understand the practical questions behind every calculation: how many litres a tank really holds, how much substrate to buy, how many fish it can support and how heavy it will be once filled. That hands-on experience shapes the guidance you read here.

Our expertise

The calculators are built on standard geometry and established fishkeeping and engineering references, documented openly on our methodology page. We pair that with clear writing so the numbers are useful whether you are setting up your first nano tank or planning a large custom build.

How we work

We follow a consistent set of editorial standards: use exact formulas, label rules of thumb honestly, cite our methods, and update content when we can make it more accurate. Reader feedback is a core part of that process.
