Calcium on rocks

So i am searching for some bigger rocks for My aquarium and all the rocks i find have small bits of calcium on it. I tested it with CLR and the whole rock doesnt foam just bits and pieces. How bad is this?

My tap PH is 7.6 and my aquarium is 6.0 do to the ada AS. The AS actually strips all the calcium out of my water and im forced to dose some gh booster as a supplement. Does this have an impact?
