I am now going to the pool store but I don't let them people sell me out. I had this pool clear without there chemicals last year and I am determined to do it again. They already tried to sell me some down and out , yellow out or something like that to help drop everything overnight to the floor this morning when I went for a stinkin leaf net. I told them no I will get it out. Then he did recommend me to shock it with 4 pounds of shock because I told them I was battling some algea bloom. I won't buy that stuff for 12.95 for 4 pounds. Thats like gas prices in the summer time to get my pool to run .LOL
