I totally agree with you. As for "burning the fish" just remove them from the tank while you add the sandAs for being harder to vacuum, actually, I think it is easier to keep sand clean because all the waste lays on top to be vacuumed up. With gravel, it filters down through the cracks and crevices between the gravel so you have to really dig down to get it and you still can't get it all.
Heh, sorry your right!Well, I don't think anyone is planning to burn their fish
I think you ment burring, and yes, thats what you'll need to do.
