The API Nitrate Test Kit is the precise and easy way of testing the nitrate levels within your salt or freshwater aquarium. Nitrate is one of the key causes of algae growth, which can be a stubborn problem.
Regular testing with this handy kit from API will safely monitor the levels so you can treat the problem before it gets worse. We have a great range of nitrate removers here at Swell UK to help you solve the issue.
The kits includes 90 tests, a colour wheel to compare results and a full booklet of instructions.
