Colombo NO3 Nitrate Test Kit

Colombo Nitrate Pond Test Kit (NO3), is produced from the breakdown of nitrite in the filter.

Nitrate is relatively harmless to freshwater fish, but its presence can indicate a deterioration in the aquarium environment, and high nitrate will encourage algal growth.

The only way to know what the nitrate level is, is by testing it with a Nitrate test kit.

Colombo Nitrate Pond Test Kit contains 40 tests.
