I think that the suff "Life" that was on the rocks that are now under the sand is rotting. I first noticed a white substance kind of patchy like that resembled wrinkeld paint when using paint stripper, that was on top of my sand. I asked Aaron about it and he said to suck it up, so I did, while sucking it up I also noticed black charcol looking stuff under the sand, and also bubbles coming up. With all that being said, will this go away once bacteria is built up? and should I wait to put a cleanup crew in?
