Tetra Pond NH3_NH4 (Ammonia) Test Kit (50 Tests)
Why Test? Within your pond, fish waste together with uneaten food and dead plants are decomposed in a process known as the Nitrogen Cycle.
This cycle involves the decomposition of fish waste etc, into ammonia, ammonia into nitrite into nitare.
Total ammonia in concentration greater than 0.25mg/l and if present for extended periods is harmful to your fish and an indicator that your biological filtration system is not working properly.
