Frequently asked questions

How do I add a tank?

Open Tanks, choose Add Tank, then enter its name, aquarium type, capacity and optional room. You can add livestock, equipment and records afterwards.

Which aquarium types are supported?

WaterChange is designed for freshwater, saltwater, reef, brackish and planted aquariums. Available parameters and care options adapt to the selected type.

How do target ranges work?

Reference ranges are selected for the aquarium type and shown beside applicable readings. They are general aquarium-management guidance and can be adjusted as the app evolves.

How do water-change alerts work?

Choose a next-due date when logging a water change and enable notifications in Settings. Delivery also depends on your device permissions and operating-system settings.

Can I manage several tanks at once?

Yes. WaterChange supports one tank or many. Multi-tank water changes let you apply one routine to selected aquariums while saving an individual record to each.

What if I do not test every parameter?

Record the readings you have. Missing readings are left unrecorded—not treated as zero. Tank Insights evaluates only usable readings with applicable ranges.

Does WaterChange work on iPad?

Yes. WaterChange is designed with a dedicated iPad layout using sidebar navigation and larger responsive content areas.

Is Android available?

Yes. WaterChange is available for Android with the same core aquarium-care experience.

Where is my data stored?

Storage and backup behaviour can vary by app version and platform. Check the in-app Settings and Privacy Policy for the behaviour of your installed version.

Not receiving alerts?

Confirm WaterChange notifications are enabled in the app and in your device settings. Focus modes, battery settings and operating-system controls can affect delivery.
