I will go back over the test to make sure but im almost certain it is right. My tank has been running for a while and i am the new owner of it. When i moved into this house i was not sure of what salt the old owner used and started using red sea pro salt. Could it possibly be that i am using a salt with a high calcium substance but just do not have enough corals to take in that calcium yet? and the high calcium precipitating and lowering my alkalinity? Seems like i read that happening somewhere but not sure.
