About & corrections
Tank Balance is a focused workspace for freshwater aquarium constraint planner.
A useful result, with the assumptions attached
Review water ranges, group sizes, tank dimensions, and unresolved behavior constraints. No opaque stocking score. No false compatibility guarantee.
What this release includes
An interactive local-first tool, editable records where relevant, CSV templates and imports, transparent result tables, optional browser-local saved plans, JSON export and restore, a printable report, and source-linked methodology. A shared backend, verified live catalogs, subscriptions, user accounts, email notifications, and independently audited source coverage are not included.
Report a correction
Use the source-code link in the footer to open an issue with anonymized inputs, the expected result, the actual result, and the method version. Calculation bugs and missing evidence should be reported separately. Source records are not altered because of advertising or sponsorship.
No invented authority
Prioritize animal welfare. A specialist-reviewed husbandry plan and a properly cycled, stable aquarium are required; this calculator is not approval to add fish. This tool does not claim certification, professional endorsement, complete source coverage, or market-leading accuracy.
