Ok I am hoping I am putting thus in the right area. My wife has 3 freshwater tanks. She is becoming annoyed that the tanks are becoming cloudy and a hazy with a film on top. She has to completely empty the tanks 100 percent water change every week now. This has just started within the last 3 weeks. When I get home I'll test parameters. But does anyone have an idea on how to stop this?
Thanks
