  • Require no chemicals or test procedures


Ammonia Alert:

Ammonia Alert’s® sensor changes reversibly from yellow to green to blue, relative to the ammonia concentration.

It detects less than 0.05 mg/L (ppm) free ammonia and alerts you to the #1 killer before any sign of stress.

The presence of the free ammonia is in fact detectable continuously with a response time of about 15 minutes.

Response to decreasing ammonia is slower, requiring about 4 hours to go from TOXIC to SAFE on removal of ammonia.

Marine or freshwater use.


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 from yellow to orange to red alerting you to shifts in pH levels between 5.4 and 8.0.

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

Freshwater use only.
