The NT Labs Marine Multi-Test Kit is a complete liquid test kit designed to monitor essential water parameters in marine aquariums. It allows hobbyists to perform up to 155 combined tests for ammonia, nitrite, nitrate, and pH, helping maintain a stable and healthy environment for marine fish and corals. The kit uses liquid reagents for higher accuracy, includes clear instructions, a color comparison chart, and a convenient test tube rack for easy testing and organization. Results are reported in nitrogen form (NH3-N, NO2-N, NO3-N), ensuring compatibility with recommended safe levels for aquatic life.

NT Labs Nitrate Test kit reports concentration in terms of nitrogen (NO3-N) to be compatible with reported safe concentrations as they apply to fish and plants. If you are interested in knowing the ionic concentration of the measured parameter, multiply your result by 4.43 (NO3-N).
