Frequently asked questions
An app to run your aquarium: tank profile, water parameters, photo diagnosis, dosing and species compatibility. Everything reads from the same profile, so the modules talk to each other.
Besides the photo, it sees your latest readings, your inhabitants and the age of the tank. So it points to the likely cause, not only the symptom.
Yes. The profile supports freshwater, planted, nano, quarantine and reef tanks.
Yes. Search for the species and the app checks it against your tank: temperament, adult size, available volume and how mature the cycle is.
No. It is guidance based on your data. If the problem continues or gets worse, see an aquatic vet.
We are preparing the app for iOS and Android. There is no date yet; the store icons in the footer signal that it is coming.
Coming soon to iOS and Android
