I have a 19,000 gallon in-ground. Salt water. I threw the hose in on Friday and left for vacation. Came home today, Tuesday, to an over flowing greenish brownish pool. I don't even know where to start. My water is very hard. Salt registered at around 1500. What do I do first? I tossed in 8 gallons on chlorine because that is all I had on hand. Please help me figure this out so I don't gotta get a divorce
