NT Aquarium Nitrate Test Kit
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). 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 etc) feeding into the aquarium, the number of fish and the amount of food fed. High nitrate levels will lead to algal 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. Remember: this plant life does include algae.

The test strips are easy to use and give clear color changes. I’ve been using this kit for three months and can now monitor nitrate levels regularly. It helps me keep my aquarium balanced and reduce algae issues.
William Gray –
Works well for checking nitrate levels. The instructions are clear and the results are consistent. I noticed a drop in algae after adjusting feeding based on the readings.

Very reliable kit. I use it monthly to maintain good water quality. The color comparison chart is helpful and the strips don’t fade quickly.
