Seachem Alert Series

Description

Ammonia Alert is an innovative color device for monitoring toxic free ammonia in marine or freshwater environments. A sensor changes reversibly from yellow to green to blue depending on the ammonia concentration. Lasting over a year, no test kits, chemicals, or procedures are needed and the device detects less than 0.05 mg/L (ppm) free ammonia and alerts you to the #1 killer before any sign of stress.

The One Year Alert Combo pack includes a year supply of Ammonia Alert (1 card) and pH alert (1 card & replacement sensor). At almost half the size as the competitor, they don’t get in the way of the view of your beautiful aquarium layout. No chemicals or test kits required.

pH Alert is a unique colour device designed to monitor pH for freshwater use only. A sensor changes colour reversibly between yellow, orange and red to alert you of pH level shifts between 5.4 - 8.0.
