Seachem Ph Alert (Fixed Ph Test) - Aquarium Water Test

Seachem pH Alert is a unique measuring device, placed in the aquarium or filter, that continuously monitors the water's pH. By changing colour, it alerts you to changes in pH between pH 5.8 and 8.2. It replaces classic aquarium tests and does not require indicator papers. Only suitable for freshwater tanks. pH Alert has an easy-to-read scale, is on average 4 times more durable than other meters of this type, and is almost half the size, so it does not take up space in the aquarium and is unobtrusive.Duration:- up to 6 months
