Hello everyone,
I have two somewhat related questions for you guys.

1. For those that use chlorhexidine, how often do you replace it with fresh solution (i.e. do you mix some every week, every cleaning, every month, etc.)? I bought a gallon jug, pump top, and the bottle to dilute it in. My problem is that with only 5 snakes and some geckos, I don't go through my diluted solution very fast and I am not sure how long it stays effective as a cleaning agent once mixed and exposed to light.

2. Do you do a complete clean out on your tubs every week / month, or just clean when they mess up their tubs? I've been removing waste / spraying chlorhexidine, and replacing paper towels / newspaper each time my BP goes (about once a week) so I am not sure if I need to break down the tub for a complete clean as well.

Thanks for your time / help!
