For the past week and a half my fishtank's water has been cloudy. I have done probably about 8 water changes trying to get rid of it. What I'm wondering is, I'm on well water, is it the fact that I'm using well water making it cloudy. Should I convert back to city water and see what that does. Well I'm going to change the water to city water and try that out. If anybody has any suggestions please let me know.
