Editorial Standards
Fish Tank Volume Calculator exists to give fishkeepers accurate, practical numbers they can rely on. These standards explain how we research, write and maintain every calculator and guide on the site.
Accuracy first
Every calculator uses a published geometric or physical formula, documented on our methodology page. We do not round aggressively or use rough estimates where an exact formula exists. Worked examples in our guides are calculated with the same formulas the tools use.
How we research
Our guidance on substrate depth, stocking levels, water weight and glass thickness is based on established fishkeeping practice and standard engineering references. Where a figure is a rule of thumb rather than a hard rule, we say so plainly and explain the factors that change it.
Review and updates
Calculators and guides are reviewed periodically for accuracy and clarity, and updated when better data or feedback becomes available. Each methodology section carries a last-reviewed date so you know how current it is.
Corrections
If you spot an error, we want to fix it quickly. Email us at fishtankvolumecalculator9@gmail.com with the page and the issue, and we will review and correct it.
Independence
Our calculators are free to use and our recommendations are not influenced by sponsors. When we link to other tools or resources, it is because they are genuinely relevant, not because of any paid arrangement.
Clarity and safety
We write for hobbyists, not engineers, and explain the reasoning behind each number. For decisions that carry real risk, such as glass thickness on large tanks, we tell you when to consult a professional rather than rely on a guideline alone.
