I'm considering using for my 150, but I've never used it before. I dont really have a filter to put it in, so I was thinking maybe I'd just stuff one of the glass spacers in my sump with some packets of it, thereby forcing all the water that goes through my sump through the purigen. (I'd probably just put one wall of it, not cram 15 packets in the entire divider) Would this work, or is purigen something you have to force water through at a higher pressure? Would this extract too much from the water?
