I have 7 snakes and while they are all in the racks now on newspaper, when I had 4 in tanks I was using ecoearth. I loved it! It held moisture great so humidity wasn't a problem even in a screened top tank, and clean up was pretty simple. the one thing I didn't like was the way it clung to the bottom of hides and the water dish. pulling those things out was a nightmare. keep a vacuum handy!
