Quick update: The temperature has been stable the last few days, no more errors, so I'm focusing on increasing the humidity with the hope of getting rid of some of the dimpling. It's been at 95% pretty consistently, but I haven't been able to get it any higher than that. I tired putting a moist paper towel on the eggs, but it didn't seem to help, so I took the plastic out from under them. They look a bit better since I took it out. The smell of fungus seems to have vanished as well.

I've been busy the last couple of days, but I think someone dug up an old thread that advised people to put suran wrap over the tub, just under the lid. Has anyone ever tried that? The thread recommended to lift the wrap every 3-5 days for ventillation. That doesn't sound like a lot to me, but if it helps I'd be willing to give it a try.
