Salifert Freshwater Phosphate (PO4) Profi Test for the freshwater aquariums, provides fast and accurate results when used to test your water parameters.Phosphate (PO4) is present our water sources and therefore aquarium. While phosphate does not directly harm your fish, even at high levels, the algae blooms that result from elevated phosphate can ultimately cause problems for the aquarium inhabitants.Green water that is high in algae can change the water pH (acid-base balance) and decrease the oxygen, which can harm the fish and even result in death.Phosphate naturally increases as wastes are broken down within the aquarium. In addition to being internally produced, phosphate can enter the aquarium from external sources. Everything from fish food to the chemicals used to buffer the water to the tap water itself can contain significant amounts of phosphate.Phosphate sources may include uneaten food, plant decay, fish waste, carbon filter media, aquarium salts, pH/kH buffers and even our tap water.Instructions: Add 10ml of aquarium water in to the test vial. Add 4 droplets of the PO4-1 reagent and swirl gently for 10 seconds. Add 1 scoop of the PO4-2 reagent and swirl gently for another 30 seconds. Place the test vial against the color chart to obtain reading. Planted fish tanks usually require a phosphate level of 0.25 – 1 mg/L (=ppm).Performs: 60 tests
