I tried barebottom but didn't really care for it. I like the look of sand , how it looks natural, and it brightens the tank. But i hate the sand storms from fish, and the constant particles flying around. So I'm starting to syphon out my sugar size sand. If i go to a coarse sand will this help with the particles flying around? i think that it would but not sure. What types of sand can i use and not have this problem? Crushed coral? The thing i worry about with a very coarse sand is detritus building up in it. Any one have experience with the coarser stuff?
