how often should you change substrate

[Freakie_frog]

good question. I have a 30 Breeder tank and I have the bottom layer paper towels...and then i have about 18-20quarts of this stuff...


I pic up poop or anything I see that doesnt look like bark. How often should I clean?

Keeping in mind that the bark isnt cheap...once a week for me at least seems very unnecessary.

Just imagine I clean paper once a week that is covered in urine and that bark soaks it up and holds in there. You can't get that out with spot cleaning so, I have found that with the bark/eco earth/aspen/coconut husk ect every three to four weeks a total change is needed. Other wise your risking the health of the animal.

just my two cents.
