I was in a pet store last night picking up pinks and fuzzers and I saw GLUB, a specially treated water created for reptiles. They only had it in a half liter and it was about $4.00 and I pretty much concluded it was junk. I've been giving my snakes spring water straight out of a bottle that I bought specifically for them. For a while I used tap water, but it can't be very good for them, it's not good for me. Has anyone ever tried this GLUB stuff? Is it fine to just use spring water? Any suggestions?
