I apologize in advance if this thread is misplaced. I have just made roughly 30-40 lbs of live rock I and it is now in leaching pales. The only type of Portland cement I could find was the type one which is dark gray. Is the coloration going to effect the curing of the rock or function of the tank regarding light absorption/refraction? The rock looks pretty good and is extremely porous.
