Phosphate Profi-Test If phosphate is present in too high a concentration there may be an increase in growth of undesirable algae and if the phosphate level is higher than 0.04 mg/L the growth rate of corals and calcareous algae may decrease by as much as 90%. Washing fish food (a rich source of phosphates) after thawing can significantly reduce the input of phosphate, and using a high grade, phosphate free activated carbon can also help to keep phosphate levels as low as possible. The Salifert Phosphate test kit detects, in less than 5 seconds, the level of phosphate present. There are two different ranges within the kit: a low range for phosphate-phosphor from 0.01 - 1 mg/L and a medium range for phosphate-phosphor from 0.02 - 2 mg/L. Sufficient for 60 tests. Can be used for marine, fresh and garden pond water Erroneous results might be obtained when the carbonate hardness is higher that 20dKH. This corresponds to an alkalinity of 7meq/l. Normally the carbonate hardness is well below the above mentioned values. Warning!Irritating: PO4-1 contains < 3.5 M HCL.R36/37/38: Irritating to eyes, respiratory system and skin.S26: In case of contact with eyes, rinse immediately with plenty of water and seek medical advice.
