I just moved in to my new house in sept. last year and my cya levels were thru the roof. I decided to wait until spring to do anything, and here i am now. So i am planning to drain my pool out and refill it, then I would like to know what step by step procedures i need to do. I am sure this info is probably posted already, but i can not find it. Please refer me the link if it is, and if not please give me the guide.
