It seems like everyone who has a problem with humidity, has a problem keeping it up. I, on the other hand, can't get my humidity down. It's at 85%, and they were just put in last night. Is it ok to just let it run until the sponge dries up? I can't really get to the sponge to drain it out, and the hose doesn't suck water back out of it, just puts it in. Any ideas?
