When tilting the tubs/incubator you will run into the risk of your eggs moving and rolling. Which will kill them if its been longer than 24 hours after they were laid.
I put 3" of vermiculite/perlite in 6qt tub. Fill it with water till its soaked. Use 2 pieces of light diffuser so it dont sink and get eggs wet. Put lid on and thats it. If still getting condensation then its a incubator problem having cool/hot spots.
Also when a egg gets wet it can sometimes cool it down and cause it to sweat which is bad.
