Okay I stalled out. I am hoping to get wet this week, but actually have to go to school. I am thinking of doing a large reef structure on one side of the tank that gradually leads to a sand flat on the other side of the tank. I am left with only my Pygmy angel trio as ick has wiped everyone else out. Right now I am trying to think of what to use to get the rock to stick together. I had previously bought two part PC-11 epoxy, but it was too thin when mixed I may try it again though. Really prefer not to pay a premium for the plastic beads. As the tank stands I will be running two the AP-700 and 2 gen 1 Radions for light. I am not growing anything challenging or light demanding so these will work just fine for my purposes. Now I just need to figure out how to program the Radions.
