Charlie, I know I'm going to get some hate mail for this, but I firmly believe in vacuuming the sand . . . nutrient exportation. And, it's not crushed coral, it's way smaller than that. I do it on occasion in my 36 and I can't believe how much junk comes out of there. That can't be good if left in there. For me, the sand just makes it look like a finished tank, but builds up too much crud beyond that and requires maintenance.
Oh, and thanks for coming over to check out the new tank! Glad you liked lunch. Yeah, it's 5° here tonight, brrrrr! Nice pic of the little guy!
