Seachem Alert Combo Ammonia & PH Constant Reading

Seachem Alert Combo – Continuous Ammonia & pH Monitoring for Aquariums

The Seachem Alert Combo is a dual-pack monitoring solution for freshwater and marine aquariums, combining two sensor-based indicators: Ammonia Alert® and pH Alert®. Designed for simplicity and long-term use, these compact, colour-changing devices continuously monitor water conditions without the need for testing kits, strips, or chemicals.

Ammonia Alert® tracks free ammonia levels, the most toxic form, with clear colour changes ranging from yellow (safe) to blue (toxic), reacting within 15 minutes. It lasts over a year and works in both marine and freshwater environments. pH Alert® provides instant visual feedback on pH shifts in the range of 5.4 to 8.0 for freshwater tanks, lasting up to four times longer than comparable products.

• Continuous monitoring of ammonia and pH levels
