I had been using a certain water conditioner/dechlorinater for a while, but when I went to get more they didn't have it, so I grabbed a different one that said it was for bettas. Recently, every time I do a water change, both Speck's and Pierre's bowls become very very foggy, and look as though they have not been cleaned. It usually takes a day or two for the fogginess to show up. I don't know what could be causing this! I am very thorough in my tank cleaning and never ever use anything other than really hot water (no bleaches, soaps, etc). Just don't know what could be causing this all of the sudden...do I need to be worried About the health of my bettas? Any ideas as far as what could be wrong?

Thanks a million
