Salifert Nitrate Profi Test

When an aquarium has insufficient regions deprived of oxygen (= anaerobic zones) or denitrification proceeds incompletely then nitrate will build-up.

A too high nitrate concentration can result in unwanted algae-growth and these might irritate corals in their neighborhood. Nitrate as such also retards coral growth.

The nitrate concentration in a proper functioning reef aquarium should preferably be lower than 1mg/L. Fish-only aquariums would usually show much higher nitrate concentrations.

Most test kits use a procedure in which a certain part of nitrate is converted chemically into nitrite and is measured as such.

Once again, just as with nitrite testing, amine interference has a major impact on the measured value. If such an interference occurs concentrations much lower than actual will be measured.

The Salifert nitrate test does not suffer from such an amine interference. The very special ingredients allow a very fast and precise measurement.

The range spans from very low to a very high nitrate concentration (approx. 0.05–20mg/L as Nitrate-Nitrogen or 0.2–100mg/L as nitrate ion).
