Why? I want to hook the system up to our central sump to alleviate the need for additional water testing, topoff, dosing, etc.
I like the Biocube but by having the systems plumbed together it gives me the convenience of one system - versus multiple separate tank systems. It should also help with the heat buildup we've experienced with nanocubes, and it should improve water quality since our sump has a large protein skimmer and other accessories that will benefit the cube.
