Hey everybody! I love this forum already...I bought a pac man yesterday according to the sales associate and everything (up until now) stated that reverse osmosis water would be just fine for my new little buddy. I just read that it isn't and in fact and eventually end up hurting him. My gut sank when I read that because is used r/o to ready the substrate and fill his bowl/mist the tank. How bad did I screw up?!? I'm really worried right now. If anyone could help am out that would be awesome!! Thank you
