Depends on the brand of paper towel too, I used one layer of Bounty or two layers of the generic stuff when I used paper towels. I actually use Prococo husk on the majority of the tub and leave a bare spot in the back over the heat source. Typically the ball python will make a mess in the back and crawl up on the coconut husk. When I check on him I'll spray down the bare bottom in the back with Chlorhexidine (diluted with water) and if the snake is 'soiled' I'll spray him down with water as he sits on the coconut husk bedding. It's been working good for me, I change out the coconut husk once a month now. I used to use paper towels when I had a mite problem, what a nightmare.
