Phosphate Test Kit AF Phosphate TestPro is designed for quick measurement of phosphate ions in a marine aquarium. Phosphate is a breeding ground for the growth of undesired algae, so it is very important to constantly monitor its concentration in marine tanks. In addition, a high concentration of phosphate may be harmful to corals. Phosphate levels in the marine...

Nitrate Test Kit AF Nitrate TestPro is designed for quick measurement of nitrate ions in marine aquariums. Nitrate in water is the end result of biological filtration. High concentrations of nitrate cause the growth of undesirable algae. Nitrate levels in reef aquariums should be 2-5 mg/l (ppm). This test kit contains sufficient reagents to perform 40 tests...
