This is the beginning of my biocube. I found that the CPR backpak fits easily into the compartment where the bioballs go. I upgraded the pump for more flow and added about 30 pounds of sand and 35 pounds of cured LR. Im gonna wait for about a month b4 i add anything. I just want everything to be well established. Its a neat little tank. The big powerhead in there will eventually be removed. I just have that in there to circulate the water.
