love my reef
OK I'm the one that is using the Reef crystals from fosters so I tested my RO water and Cal and KH came back 0, then I mixed up some of my salt and tested again CAl came back 520, KH came back 16 drops! WOW!! so now what is a good kind of salt mix? I'm going to the LFS in the morning and see what they have..
