Summarized by Shop
Phosphate in natural sea water ranges from less than 0.01 mg/L to 0.3 mg/L. For corals in reef aquaria, such phosphates should be 0.2 mg/L or less. Phosphates are non-toxic to fish and most invertebrates, but are ideally kept below 1 mg/L to minimize algae growth. In freshwater, phosphates are not critical and the allowable concentration
