LOL. In the sump I want a skimmer, heater, and mainly a refugium. I want to run carbon, I always have, that's why I thought of the media basket. So, even the tank dividers that they sell wouldn't work. Reason I ask is that a lfs has some on clearance, for dirt cheap, and they have the grooves, holders, whatever they are that come with it to hold it in place. I wasn't sure if it would hold up, but then again, I don't know much about sumps.....
