Nitrate Test Kit

The NT Labs Nitrate Test provides a simple, easy to use testing kit for determining Nitrate (NO3) levels in both ponds and freshwater aquariums. The NT Labs Nitrate Test Kit comes complete with test tube and liquid reagents to provide accurate results for 30 tests.

Nitrate is produced by the beneficial bacteria in the aquatic environment and filters as they break down the fish's toxic waste products, Ammonia and Nitrite. Nitrate is not typically toxic to fish, but excessively high levels can promote unwanted algae growth.

What is Nitrate?
Nitrate is produced by the beneficial bacteria in the water and filters as they break down the fish’s toxic waste products (Ammonia and Nitrite). Unlike Nitrite, Nitrate is not typically toxic to fish, but excessively high levels (>100mg/l) can cause problems with growth.

What is the correct Nitrate level?
The level of Nitrate is dependent upon a number of factors, including the Nitrate level of the tap water or spring water used for water changes, the number of fish and the amount of food fed. High Nitrate levels will lead to unwanted algae growth. A Nitrate level of zero is ideal and implies a balance between waste produced by the fish and nutrients taken up by the plant life. Just remember: this plant life does include algae.

What do I do if the Nitrate level is wrong?
Maintenance of a zero level of Nitrate is extremely difficult. Most domestic water supplies have a low level of Nitrate. The key to maintenance of low Nitrates is regular water changes to dilute the build up of Nitrate.
