API Phosphate Test Kit
Phosphate Test Kit tests phosphate levels in aquarium water, fresh water and salt water, from 0 to 10ppm.
Phosphate can enter your aquarium through tap water, fish waste, and decaying organics such as uneaten food and dead algae. Excess phosphate contributes to unsightly algae blooms. In saltwater, excess phosphate can inhibit the growth of hard corals. This kit tests phosphate levels from 0 to 10 ppm in fresh and saltwater aquariums.
Kit contains: 2 bottles of liquid test reagent, 2 laminated, computer calibrated color cards, glass test tube with snap-tight cap, step by step instructions and information on how to correct unsafe conditions.
