Top Reef is the control app for Top Reef aquarium equipment. You need a Top Reef device to use it — without one, the app does nothing.

WHAT YOU CAN DO

• Dosing pump (DOS)
Set what each pump doses and when, keep an eye on how much is left in each bottle, and get a notification before a bottle runs out. A single glance tells you whether everything is still running.

• KH Keeper
Track the alkalinity (carbonate hardness, KH) of your water. See the latest reading and the trend in a chart, and start a measurement whenever you want. The KH Keeper can also adjust your dosing pump automatically.

• Temperature control
See your water temperature, set your target, and let your heater or chiller switch automatically. If the temperature moves outside your alarm limits, you are notified straight away.

• Calibration
Measure how much a pump actually delivers, so your doses are accurate instead of approximate.

AT HOME AND AWAY

At home, the app talks to your device directly over your own Wi-Fi — even if your internet is down. When you are away, it uses a secure cloud connection instead, so you can keep an eye on your tank from anywhere.

NOTIFICATIONS THAT MATTER

You get alerts for the things you can act on: a bottle running low, a temperature outside your limits, a device that has stopped reporting. You decide what you want to hear about, for each type of alert.

UPDATES WITHOUT CABLES

Install new device firmware by scanning a QR code. No cables, no computer.

25 LANGUAGES

The app is available in 25 languages and follows your phone's language setting automatically.

ABOUT YOUR DATA

We show no ads, we do not sell your data, and we do not track you across other apps. Your device PIN codes and your Wi-Fi password stay on your phone and never reach us. We do not collect your location: Android requires that permission only so the app can show you nearby Wi-Fi networks while you set up a device.

You can delete your account at any time, in the app or on our website — either way, your data is erased.

Top Reef is made in Belgium.
