I use perlite, you can get a huge bag of it ordered through Home Depot pretty cheap, if you look it up at HD online it comes in a generic looking green bag...the one I ordered turned out to be about the size of a 30gal kitchen trash can. Had I known that when ordering, I wouldn't have ordered two...lol. I put about two inches of perlite in my egg boxes, fill water about half way up the perlite, one layer of light grate on top of the perlite.

I tried substrateless, water only, with no mold problems for nine eggs. I attached plastic canvas (available at craft stores or WalMart) using the smallest plastic wire ties I could find tightly on top of the light diffuser, as the holes in the light diffuser looked to me like they were big enough for a hatchling to slide through. With a tight-fitting lid on the egg tub very little water was needed to keep 99% humidity, so no worries about splashing either.

I did read somewhere that using sand or aquarium gravel is a good idea not only to prevent the water from splashing, but also to add more thermal mass to the egg tub. In case of a power outage, the sand or gravel would help maintain the temperature for a while so there would be less risk of losing the eggs.
