Should i change the bark in my snake's tank?

[ch312]

Pricey? What kind of substrate are you using? A bag of aspen and 4 snakes will last me 6 months with full monthly cleanings and spot cleaning. $13

And unless you want urine baked bedding, than go ahead. Baking may kill bacteria, but probably not all of the other things in feces and urine.

its $30 something dollars for a large bag of reptile bark. i think it maybe even be over $40 after taxes...

notice how he was asking about changing BARK not ASPEN?
