Please tell me if this all looks OK. Eggs are coming today or tomorrow and I'm freeeee-kiiiiiiing (in a good way). I've been running it for a couple days working on getting everything just right. Thermometer w/ probe on top. Interior. There is a big pan of aquarium rocks in a plastic bag for heat storage and stabilization... Hopefully if the power goes out at night, the eggs will stay warm for a while. And I couldn't find a water wiggler so I used those water crystals for the garden in a baggie, with the thermometer probe folded inside. Walmart's sponges were the ones that said "NOT SAFE FOR AQUARIUM USE" so I used a folded microfiber cloth instead. Hope that's OK? I wasn't sure... Do I leave the airholes covered for the first 18 days? Anything need adjusted, other than my head?
