Phosphate can enter your aquarium through tap water, fish waste, and decaying organics such as uneatern food or dead algae. As phosphate increases so does your chance of having unsightly algae and green water blooms. High levels of phosphates are also  harmful to plants.

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.
