API Phosphate Test Kit
Phosphate can enter your aquarium or pond through tap water, fish waste, and decaying organics such as uneaten food and dead algae. Excess Phosphate contributes to unsightly algae blooms in aquariums and ponds. In salt water, phosphate can also inhibit the growth of corals and other reef building organisms. This kit allows you to easily and accurately measure the phosphate level and maintain a healthy aquarium or pond.
