Anyone have any ideas why my alk is going up with no dosing? Calcium 400 , mag 1300, all was 9.5 now 11.2 . This has been over a few days, only thing new is a fake rock I bought . Could that be it?
I just used baking soda to maintain alk at about 9.0-9.5 ,been doing that for months no issues
It may be helpful to test the alkalinity of the fresh water that used to mix salt.I was dosing regularly with baking soda to keep Alk at about 9.5 with no issues . I think changing to reef crystals might be culprit I tested water i made for water change and the alk was 16
