The API Freshwater/Saltwater Phosphate (PO₄^3-) test is a great asset when attempting to eradicate nuisance algae. Phosphate enters the aquarium through tap water, fish waste, uneaten food, and decaying algae. When high phosphate levels spur the growth of nuisance algae, it also inhibits the growth of freshwater plants and desirable marine algae. Quick easy and accurate with up to 150 tests.
