So I was looking through my mistking manual and seen the list of waters that can be used and then I started thinking what if the drinking water for my herps isn't safe. When I bought my first herp I bought the zoo med water purifying blue stuff and it said on it use with tap water so I thought I was all good. Now I'm worried that I'm not and beating myself up for not looking into one of the most important things to there survival. They show no signs of health issues so it must not be hurting them, I hope. I use tap water, not city tap water well water along with purifying with the zoo med stuff. Is this ok? Should I switch? What are my best options? I'm sure ro is the best but the systems are pricey. Would a Brita purifying system be good enough with my tap?
