My pool turned into a frog pond here lately. (hurricanes, pump quit, ad infinitum, ad nauseam ) and I want to clean it up before covering it for winter. That means ph up, down, up, down,--
I have to drive 20+ miles to get to the store for the acid so I want to be sure to get enough to do the job so I don't have to make another trip just for that. But if it isn't going to last out the winter I sure don't want to buy too much! (I'm considering buying 10 gallons)
So will sealed plastic gallon bottles of Muriatic acid last, say, through next summer?
