Seachem pH Alert

pH Alert™

pH Alert™ is a unique colour device designed to be placed in the aquarium or filter and monitor pH continuously.
A sensor changes colour reversibly to alert you to shifts in pH levels between 5.8 and 8.2.
No tests, no strips — just constant readings. Freshwater only.

Why It’s Different

pH Alert™ lasts up to 4 times as long as competing products.
pH Alert™ is also almost half the size of competing products.
It’s small, clear, and unobtrusive, so it won’t detract from the view of your aquarium.

Directions

Simply place pH Alert™ visibly anywhere in the aquarium or filter. It’s that easy.
No chemicals or test procedures are required.

When first put into service, response time will be about 30 minutes.
Thereafter, pH shifts will register within ten minutes.
