Had a doser malfunction that dumped monosdium phopahte in my 225 gsallon reef... after changing over 225 gallon of water over a week the phosphates are still 0.90 and not budging.. the sample water turns blue soon after adding the reagent. I moved all corals to my other system for now, the phosphate in that system are 0.06. what can i do to lower the phosphates in the 225 gallon back to 0.06 ??? please help and thanks in advance. regards, D.
