Should I remove my shallow sand bed - issues in tank

[Myka]

Yeah, that is a lot of rock, and it looks like you have it leaning against the back glass. My own rockscape "rules" are, don't lean it against the glass, don't go higher than 2/3 the height of the tank, stack it loosely making lots of tunnels and caves so water can flow through it well, and place it so as little as possible is touching the sand. What I mean with the last part is that each stack I make a tripod-style (or quadpod lol) base and then stack the rocks on top so the majority of the rocks are above the sand rather than in it. Creating your rock structures using these guidelines will make keeping your tank clean much, much easier. The corals looks really great in your pic though!
