So, we had trouble keeping Dex's moisture level in his tank, so we came up with the solution of a wet towel covering part of the top grate. This worked well for a while, but over winter and with the furnace running the towel dries out when we're sleeping or at school. So we decided to put in this fancy pants waterfall a friend passed onto us. We've taken precautions to make sure he can't get into the machinery, honestly he's too big to fit in there, but we laid glass aquarium pebbles around the pump just in case. The water is filtered, just like his drinking water. I think we've covered all bases, but I figured I'd ask the experts just in case. Thoughts? Advice? Opinions?
