SALIFERT PHOSPHATE PO4 PROFI TEST KIT. • The Salifert Phosphate test kit detects, in less than 5 seconds, the level of phosphate present. 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%.
