How do dosing recommendations work?
ReefLog learns from your own readings. Add a supplement and calibrate it once (dose a known amount, re-test, enter how much the parameter rose). ReefLog then uses your tank's measured consumption trend to recommend maintenance and correction doses — never guessing a product's strength. Always dose gradually and re-test.
Is my data backed up?
ReefLog stores data locally on your device for privacy. Deleting the app removes its data. Use the CSV export to keep your own copy.
What does the premium upgrade include?
Everything in ReefLog is free for a single tank — full reading history, trend charts, the dosing planner, maintenance reminders, and CSV export. A one-time purchase adds unlimited tanks so you can track every system you keep. It is not a subscription.
Why isn't my trend showing?
Trends and dosing suggestions need at least three spread-out readings for a parameter. Keep logging your weekly tests and they'll appear.
