I reaquascaped my tank this morning. I am much happier with this setup over my old pile of rocks.
This version has a very large cave in the centre when viewed from the side(the pic doesnt show it very well)
I also feel I have more space to mount frags, and I almost totally hid both powerheads, espacially my Seio620.
I have also included a pic of the little frag shelf I made out of white light difuser. I hated having zip ties on my old shelf, so I used a styrene welding solvent to bond the pieces.
