    Maybe a blend? If you need more Ca Oceanic has more than you might ever need and it has so-so alk. I have to add a little buffer each time to increase alk as well as pH.

      im just having a problem with high alk in my salt mix and would rather have low alk values in my salt mix a dial in my reactor to stabalize it much easer to raise than lower

        Oceanic is a little low. I mixed a 55g batch yesterday and it was about 6. Little low for me so I add baked baking soda which also bumps up the pH to around 8.6.

          First batch of the SeaChem Reef salt for me was 9.6 alk and 425 CA. FWIW
