Hi everyone. Thanks for the help!

To answer a couple questions - the probe of the thermostat is in the incubator, not the tub. And Pit, the eggs are not quite candling solid yellow. They are actually candling a little better now that I am using a stronger torch. It's weird though, I think the mold made the membrane harder to see the veins through. One is not candling too great, might be a loss.

We wiped the mold off of them with paper towels and put anti-fungal athlete's foot powder on them. We even put them in a new tub with new substrate, so we'll wait for now. Thanks for the advice everyone. I will check out the substrate free incubation techs too.

If anyone else has pointers, let me know!
