Since I moved to a town less than an hour away, Hoshi's tank water gets really gross in about 2 - 3 days.
A clear/white film develops on the surface of the water, and gradually spreads until it is solid across the whole surface.
It looks clear, but when I scrape at it with something, it sort of folds and crumbles into a milk-white substance. It literally looks like water that has frozen over, and then you can sort of scrape the "ice" off. :s
What is this, and how can I get rid of it? This has never happened before, so it must have to do with the new water source, although I have heard it has the same mineral content as the water in the next town over....
Thanks for any help.
