My only qualm with airstones is that when I stir the res, they move around, and if I glue them down, I can't take them out to clean them. I have looked at the flexible tubes, but do they sink? It looks like they would float from the pics...? :wtf:

I think I also need some small time odor control. The living room sits directly above my garden and with less than 2 weeks to go things are getting pretty stinky. Is there an effective air freshener I can put in the room to help with the odor? I have my exhaust fan running into my chimney as of now but apparently that isn't enough to combat the smell.
