API Phosphate Test Kit 150 Tests for Freshwater and Marine Aquariums PO4
The API PHOSPHATE TEST KIT tests phosphate levels from 0 to 10 ppm so
that you can easily monitor the condition of your aquarium water and may
be used in both fresh and saltwater aquariums.
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 and green water blooms, and in saltwater,
excess phosphate can inhibit the growth of hard corals.
