Description
ZOOLEK Aqua Test NO3– is used to determine the nitrate concentration, the final product of the nitrogen cycle, in the range of 0 – 150 mg/l. Simple measurement is carried out by adding suitable reagents sequentially to the measured water sample according to the instruction and then matching the obtained colour with a corresponding colour scale to read the result.

Why measure nitrate content?
Since nitrates provide ideal conditions for algae growth, its concentration above 40 mg/l is undesirable and has adverse effects on aquariums and garden ponds. The nitrate concentration above 80 mg/l becomes harmful to fish, whereas the levels above 120 mg/l are not acceptable in fish tanks due to its highly negative effect on aquarium inhabitants. If the concentration of nitrate is above permissible limits, that is the indication of the presence of protein waste substances in excess. Although nitrate present in aquarium water is much less dangerous in comparison with ammonia and nitrite, its content should be controlled and limited in time.

How to prevent excess nitrates?
In the case of nitrate concentration being above 40 mg/l, a partial or almost complete water change is required depending on how much the acceptable threshold is passed. An excess of nitrate shows the need to clean a fish tank, a substrate and filters. Sometimes, the number of fish in an aquarium should be limited as well.
