Instructions and Recommendations

Why test for nitrite?

Within your aquarium, fish waste together with uneaten food and dead fish or plants are decomposed in a process known as the Nitrogen Cycle. This cycle involves the decomposition of fish waste etc. from ammonia, ammonia into nitrite, and nitrite into nitrate.

Ammonia, nitrite and to a lesser extent nitrate are harmful to the fish in your aquarium, but should not reach dangerous levels if you have a suitable biological filter.

Nitrite is formed during the second stage of the Nitrogen Cycle and is harmful to aquarium fish and invertebrates. Even low levels of nitrite in aquarium water can adversely affect your fish, causing them to gasp at the water surface and become very lethargic.

In severe cases long term exposure to nitrite can be fatal.

Therefore it is important to test the level of your nitrite regularly, to ensure optimum water quality, weekly testing is recommended.

Tetra Test Nitrite Refill kits are also available in 20ml bottles
