I need some advice from some experienced herp-lovers. I have had three turtles for years and i always used an overturned frisbee for thier waterdish. then i recently got back from overseas and i expanded thier bath to a large rubbermaid container w/ smooth large rocks at the bottom and some ramps to get into it. I also put in an airstone to make little bubbles, the idea was to make it kinda realistic like a stream or something.
The problem came when one of my poor little turtles died. She was in the water all the time, she loved it. She loved the bubbles and didn't like it when i took out the stone even to clean it. I changed the water at least every other day depending.
My concern is the water. I know that i have "hard water" here (i just moved accross the country after getting home). I don't know what that means though, is it a mineral problem? is it a ph level problem? What should i do? should i get a ph level tester or are there any kind of aquerium products or anti-bacterials that any of you use in your turtle baths?
