TankStockPilot publishes an independent aquarium planning calculator and a practical journal. The goal is to make the input, arithmetic and interpretation boundary visible, so a visitor can reproduce a scenario rather than accept an unexplained number.
What this site helps you check
Estimate rectangular tank water volume from the actual water line, then build a species-by-species planning record. The planner keeps quantity separate from compatibility and welfare checks.
The Tank Volume & Stocking Record Planner explains its units and method. The supporting journal guide follows an input record through a comparison. Default values are labeled as illustrations, not universal recommendations.
Know the boundary
No fish-per-liter rule, compatibility score or stocking approval is generated. Volume alone cannot establish suitable space, group size, filtration or welfare for a species.
External dimensions and advertised capacity can describe the glass envelope rather than the filled habitat. Measure the actual footprint and intended water level. Leave equipment and safe headspace as practical checks. A longer tank and a taller tank may hold similar volumes while offering very different usable swimming space.
Preparation and responsibility
Initial text was prepared with AI assistance. Worked-example arithmetic is checked against the calculator during development. We do not claim a professional inspected your situation or that a referenced publisher endorses this website. The operator should review content and actual installed services before launch and after material changes.
