I would completely remove the bioball setup and just put in a tank with no baffles. Load it with brand spanking new dry sand, and fill it with ESTABLISHED LR. Have your input on one end, and put a return on some rock on the other side. Very simple. Then you can add a clamp on light and some macro and that's all you need!

If you want to come by and see my setup just call me. 209-1233
