Thanks for the suggestion on not using the repti-carpet, I'll keep that in mind when it comes to changing substrate.
I got a spray bottle from Dollar tree for...$1, its a 24 oz bottom if im correct and has a mixture gauge on the side to determine mixture levels and 'full' level. I believe that should work well. Do you know what chemical decreases the life of the chlorhexidine gluconate? All tap water is different as far as chemical composition.
