Well I'm brand new at pools, but I will say that I have followed what advise is on this forum and my pool is beautiful. I'm still in the beginning stages of building up my cya so I am adding chlorine daily. I have spoken to family members who use the pool store method and they shock about twice a week to keep the pool from getting cloudy. I know they have spent in the hundreds of dollars. I've probably spent about 40 dollars or so. If He would read some of the posts here of ones who have benefited it may help. Sometimes you have to see for yourself about things and no one can tell you differently. My pool is 33' round and holds 25,700 gal. of water. It has never been cloudy yet. Although we haven't had much of any rain. That may make a big difference. Hope things work out well! Sharon
