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.

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.
