Get an accurate read of the PO4 levels of your aquarium with the ASF SEATEST PO4- (Phosphate) Fish Aquarium Water Test Kit. Phosphate (PO4) is the result of the breakdown of uneaten food and waste, etc., and it can cause algae growth. Values should be kept as low as possible, but anything up to 0.5 mg/l is tolerable. Phosphate also tends to form insoluble salts which can form on the bottom of aquariums with the silt, and you should regularly remove it, in addition to keeping a close eye on the overall measurement.
