The build up of nitrate can result in unwanted algae growth and the slowing down of coral growth
The nitrate concentration in a reef aquarium should be lower than 1 mg/L, although fish only aquariums would usually have a higher concentration
Just as with nitrite, many nitrate test kits are prone to amine interference which can make the levels of nitrate appear much lower than they actually are
The Salifert test kit does NOT suffer from such interference and gives accurate and quick results with a total testing time of less than 3 minutes
The test kit’s range goes from a very low to a very high nitrate concentration (Approx. 0.2 - 100 mg/L as total nitrate)
