So I just rescued 4 half dollar sized red eared sliders and yellow bellies. I'm not prepared for them right now... I'm currently living in the spare bedroom at a friends house while my boyfriend and I close on our house. So right now I have a rubbermaid for them, but I do have a 30 gallon in storage for them when we close on the house. My question is, there is no none water area in the current rubbermaid for them. I live in Hawaii and have the large lava rocks in my backyard. Can I boil one of them to clean it and put in their or will it leach bad stuff into the water?
Thanks,
Logan
