Hello everyone Please help me! I have just finished setting up the Walmart Intex above ground pool 22x52 I have a sand filter set up and have always used the Krystal Clear Salt Water System again another Walmart product, however I keep having to buy one every year, because it stops working unexpectedly. So now I am going back to Chlorine. Here is the problem: My late husband always took care of the pool. I am new with all of the this stuff and I don't know where to begin or what I need to get this pool ready for my daughter's birthday party. Please help.......I am desperate! - Thank you for any help you may supply.
