Seachem MultiTest Phosphate wood Synthetic granular ferric oxide (GFO)Seachem MultiTest Phosphate Test Kit 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 is dependent on variables such as nitrate, manganese, iron, and vitamin
