Nasty Water Bowl

[ScalelessTime]

I have a waterbowl that is looking like it has some sort of chemical inside it. The water has a rainbow effect reflection in the light. I haven't seen my snake bath in it at all. I am just worried that something inside the tank or in the atmosphere is affecting the water. My other snake has a small waterbowl that I have to constantly refill and I haven't seen the same issue with it's. I am just a little worried about my snake drinking from this waterbowl.

I don't know if I have to clean the bowl more often, clean the cage more often, or what. The only new things that I have added to my room was a propane heater because the house's heater was down on 5 degree nights. I am going to do a full scrub-down tomorrow on both of my snake cages because it is getting time to do them. Maybe after that, I can calm down and see the results after cleaning the bowl. But if anyone would like to offer some suggestions on what might be causing the discoloration, please do.
