There's already a little too much (again, never used it before so it was very trial and error on my end). If I add anymore there's basically no room to fit amenities since the tub is rather shallow.
I could take most of it out and mix in dried chips, but then I don't know what to do with what would be taken out. None of the other animals I have would have a use for it so it'd essentially be wasted unless I can just set it out somewhere to dry out over a longer period of time and "reuse" it when the substrate needs to be changed out for cleaning.
