I'm not having a good day. I got a new filter bag of purigen for my 12g nano and put it in the sump area. Well, next thing I know purigen is everywhere! The top of the bag wasn't totally sealed and now it's floating in the DT area. Sigh. Should I just let the filter pick it up? Could it harm my fish or shrimp if they try to eat it? I'm having a terrible tank day.
