Ok, well this is kinda an ongoing debate/question that me and the lfs guy are trying to figure out. In the directions for biocalcium it says to "sprinkle" the powder on the surface of the water. Well, neither I nor the LFS guy like this idea so we would always premix it with RODI water and then add to tank. I was actually using it mixed in with auto top off water. The other day he ways that he talked to another customer who read on a message board or heard from a chemist or something else of the sort that if premixed it bonds with free carbonate ions in the water to form CaCO3 and actually sucks additional Ca out of the water. This could also explain why I have experienced problems with the sand clumping in my tank. We are trying to get in contact with people from TropicMarin or whatever the comp that makes biocalcium is and find out if there is any truth to this. In the meantime I figured I would consault the gurus on this board and see what you guys thought...........
