Lynnybug55,
Wow, I feel your pain! About 2 years ago, I was like your husband. Bought a house with a pool, quickly turned to the "experts" at the local pool store. After all, its what they do for a living, they wouldn't possibly stear me wrong right? Well, after a summer of spending more money than I care to admit only to swim in a cloudy/green/smelly pool, I gave up. (I've spent less $ on my SWC and Robotic cleaner than I did on Chemicals that season) I turned to the Internet and discovered the magic of SWC systems. Bought one on Ebay, then stumbled across this site while searching for information on how to hook it up.

Long story short, my pool has been crystal clear since then Luckily, it sounds like YOU already knew that. I suggest you go on a nice shopping spree, spend $500 on yourself, then take control of the pool maintenance again. Tell him that every time he goes to the pool store, you go to the mall

PS, my parents got 17 years out of a vinyl liner, his pool guy told him it was the longest he'd seen one last in a long time. You should be proud of your 15 year liner! Good luck...
