My turtle is getting very very small white spots on her shell I know it is fungus or anything like that, I think its due to having hard water. Here in az the water is very hard, I only know that because many people have water softeners in their homes. What can I due to help this, I saw once that petco sells salt water for freshwater tanks. I asked what it was for and the guy told me its like a water softener.
Will that work or any other ideas?
