Phosphate has several negative effects if present in a too high concentration. First of all undesirable algae growth might result. Making an aquarium an unpleasant sight.
Phosphate also blocks or retards the growth of corals and calcareous algae.
One of the scientific studies shows that a phosphate concentration higher than 0.05 mg/L decreases the growth of calcareous algae by 90%!
Washing fish food, which is a rich source for phosphates in a sieve after thawing reduces the input of phosphate tremendously. Also avoiding use of phosphate-rich low-grade activated carbon helps keep phosphate levels as low as possible. Checking the activated carbon for phosphate prior to use is therefore highly recommended.
Since phosphate can have major consequences when present in a concentration above 0.05 mg/L a test kit should be able in detecting even lower concentrations.
The Salifert phosphate test already detects, within seconds, 0.015 mg/L of phosphate. This makes phosphate measurement highly reliable and informative allowing timely measures to be taken. The kit can perform approx. 50 measurements.
Nitrate testing
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 1 mg/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.
Conclusion:
Many nitrate test kits are prone to amine interference. This can give results much lower than actual.
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 – 20 mg/L as Nitrate-Nitrogen or 0.2 – 100 mg/L as nitrate ion).
The kit can perform approx. 60 measurements.
