Seachem pH Alert

The Seachem pH Alert allows you to continuously monitor the pH of your freshwater aquarium water without worrying about tests and strips. It allows you to monitor between 5.8 and 8.2.

Seachem's pH Alert uses a smart colour-changing sensor and lasts up to four times longer than competing products. And best of all because it's small and clear it won't spoil your view of your aquarium.

All you have to do is place it in your aquarium and after half an hour it will start working and then pH shifts will register in 10 minutes. Use a suitable aquarium buffer to adapt the pH level to the correct one for your aquarium.
