The build up of nitrate can result in unwanted algae growth and the slowing down of coral growth. 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).
