I love it. It definitely makes life easier. Like jcook said, your alk and calcium consumption might not be balanced but that’s easily corrected by dosing a little bit of extra alk or calcium separately when you need it. The only thing I wish Tropic Marin would change about All For Reef is I wish there was a high PH option similar to kalk. As it is, All For Reef tends to drop your PH slightly.
