Your opinions regarding bare bottom vs shallow sand bed vs deep sand bed

Tried going bb but didn't like the look for my reef tank & the brain coral was getting damaged from rubbing against glass (flow is fairly high in the tank but directed well above the brain). Now everything & everyone is much happier with a thin layer of sand. I got a sand-sifting sea hare (I call it a sea mouse) which is dark grey-brown with tiny green spots to keep the sandbed clean.

My personal opinion is if you are going to put sand in, be prepared to vaccum it. I don't think we can possibly get enough bio - diversity to break down every critters waste. So, it still builds up regardless. It just takes longer to build up with a sand bed with critters.

I have a two palm sized brain in my BB tank and have not noticed any damage to it.
