I have aspen in 1 tank and turf in 2 tanks. I love the turf better! You can see the poo easy and just pick it up and throw away. Once a month I take out the turf and put them both in the washer for pretreat with bleach. I put the water on low and let them soak for a couple hours, then let it process for 4 minutes. Spins most of the water out then I hang them up. They are completely dry and sterile by teh next day.

For me the aspen is messer. I have it for my corn snake. She likes it.
