Does anyone know the impact of high Phosphate (3.0 or higher) on fish health? I have a test tank with a peat/vermiculite/clay mix and have found Phosphate readings (Red Fish Pharm) around 2.0. After transfering the plants to the new tank (so I see the root development) I will report to the list on the results. Thanks, Rochelle Williams williaro at ftmcphsn-emh1_army.mil
