I have been very impressed with what I have seen and heard about TBS and am thinking of getting the package when I finally get moved and crank up my 29 Biocube. My question is this, the package directions talk about running a skimmer, which the biocube lacks. I have thought about chopping up the lid to make access, but would like to avoid that if possible. Has anyone had success with the package in a stock (non-skimmed) all in one tank like the bio cube or nano cube? Thanks.
