I just picked up a new one cuzz the old one my dad brought home didn't seem to be doing a whole lot. but I have the whole tank basically closed off. so there shouldn't be much of a problem. tomorrow I'm going to open it up and air rate it and clean it out. I just wanted them off and dead so i can reuse the plants, that's it. The tank itself will be cleaned out with vinegar and water, left to dry then Wednesday or Thursday night hopefully some things will git moved to my new place and I will be setting them back up.
