The Alert Combo combines the pH Alert & the Ammonia Alert into one pack.
pH Alert
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.
Lasts 3 to 6 months 4 times longer than competing products, also half the size.
Ammonia Alert
An innovative colour device for continuously detecting and monitoring toxic free ammonia.
A sensor changes reversibly from yellow to green to blue, relative to the ammonia concentration. No test kits, chemicals, or procedures are needed. The device detects less than 0.05 mg/l (ppm) and alerts you to the NO.1 killer before any sign of stress.
It lasts over a year and is for Freshwater use only.
