I don't know if anyone else had condensation issues while hatching. I noticed that I was unable to see through the window on my homemade bator. Especially when I upped the humidity. My solution: this great new fishtank cleaner. Sold at most pet stores, and I picked mine up at wally world. It's a magnet, one side has green felt, the other has yellow. You just put them on the window, one inside one outside, and gently run the top magnet over the window. The bottom magnet follows, and the condensation is wiped off. These are quite heavy duty, as I was worried the inside one would fall off, but you have to pull the top magnet hard before it will release. Hope this helps someone else out. Oh, and I will be re-using mine for the turtles!!! Steph
