Right now I am using HWreefer, my only concern with it is my alk is pretty low. I have a 30 gallon, with a few lps, just starting out. I did a five gallon change, Tuesday. Do at least twice a week, as of now. Tested my alk wed and it was 7.5, tested it today and it was 7.3. HW claims I think 8.5 alk mixed at 1.025. So it's not terrible high out of the box, right? I was thinking about switching to Red Sea coral pro, which has a much higher claim of alk. I have a unopened bag of HW, and don't want it to go to waste. So can I mix the two? Should I stick with what I have?
