Features
Read full description

Keep a sequence of planned and performed water changes, compare nitrate dilution estimates with actual after-tests and preserve the assumptions behind the plan. HOW IT WORKS 1. Open Tools and Water Change Journal. Verify net water volume, starting nitrate reading and its date. 2. Add changes with replacement volume and source-water nitrate. Mark a change performed only after doing it, and add an optional actual after-test. 3. Review the chart and sequence, save the journal and share the record. Tank records, tests, maintenance tools and references remain available. The calculator now flags source water that cannot reach the requested nitrate target. An unreadable tank store blocks replacement and preserves the original file. WHAT TO KNOW Dilution assumes uniform mixing and no new nitrate production or removal between steps. It is a planning estimate, not a recommendation about a safe change size. Actual after-tests become the next starting value. Use measured net volume. Up to 12 changes per journal and 100 journals. pH is no longer offered as a linear dilution calculation. iPhone and iPad.
