Ohhh no, no chemicals for me, I kind of plan on keeping at least some inverts in there.. at some point.
I'm believing what flaringshutter said about copper leaching into driftwood, ect, so I think I'll just keep them in there, they arent really an eyesore, I just remove them when I see them. Ill probably try the cucumber idea.
I kind of like having a little almost invisible cleanup crew.
