## What is Aquarium Journal?

Keep a clear record of your aquarium, from today’s water tests to the work you did last month.

Record temperature, pH, nitrite, nitrate and phosphate together. Each saved value keeps its measurement date, so you can see how recent it is. Add maintenance events, inhabitants, notes and optional photos to your tank’s history.

Explore your own readings over 7, 30 or 90 days, with event markers and a factual table. Export four CSV tables for use outside the app. Save and restore a versioned JSON backup of journal records and saved photos; review accepted, duplicate and conflicting records before importing.

Works locally without an account. CSV is export-only. JSON backup does not include app settings or unfinished drafts. Aquarium Journal records observations; it does not provide care, dosing or veterinary advice.
