For the past 8 months of having my reef tank setup, I have been doing a 10-15% PWC once a week on my tank. This was mostly to keep Ca and Alk up as I wasn't dosing.
Now I have added a 2 part autodoser, and my test results are in the optimal ranges across the board...
0 NO3, 0 PO4, 420 Ca, 10dKH...
This is before doing my weekly water change this week... so can I reduce my PWC frequency now that things seem stable? What do you all do for water changes? How often? I realize that replenishing some trace elements is also important, but if I can reduce the water changes (and save myself time and money on salt mix) I would love to.
