Tropical TEST NO3

TEST NO3 – Nitrate Test KitA test kit for measuring the concentration of nitrate (NO3⁻) in freshwater and saltwater aquariums. It measures nitrate levels within the range of 0–100 mg/L. This test is convenient and extremely easy to use. Simply add the reagent solution drop by drop until the sample changes color, then compare it with the provided color scale.
Nitrates originate from fish excreta, uneaten food, and other organic waste that accumulates in the aquarium and is broken down by bacteria. When nitrate concentrations rise to dangerous levels, they can cause excessive algae growth. Systematic monitoring of nitrate levels helps prevent conditions harmful to fish.
