Going to close the pool sometime at the end of this month and was wondering what to add to get me through the winter and not have a swamp in the spring.

When I opened it this spring it was really bad. I had curtains of algae floating around and probably 2x2 sheets of them. Maybe I opened it to late but it was mid May.

My co worker says his is clear in the shallow and just cloudy in the deep end in the spring. Mine was not even close to that. He said he buys some kit at the pool store with some super shock and algae stuff for 60 bucks. I wanted to tell him he was probably a super sucker. Anyway whats the best thing to do for the hard central NY winters? Since I have had the pool for a few years the opening has always looked pretty bad. I usually dump 5 gallons of the store chlorine and call it a day. They have the higher concentrate.
