Re-think using these guys. Looking at the reviews, who's Brandon, which is my point. I have had 4 different techs servicing pool. The last straw was the pool turned green, then they added 4 gallons chlorine, then informed me the CYA was too high, which caused the problem. The pool was re-done less than a year ago and had fresh water. Now they tell me I need the pool drained at a cost of $450. They add the chemical and ran up the CYA within 6 months. Add that to the 4 gallons of chlorine, in addition to weekly chlorine tabs, and yes, quite a mess. Also, I have a variable speed pump, and they no idea what settings for rpm and hours for circulating to keep pool clean. Then the auto fill switch went out on a new pool? Shawn is the person who I tried to communicate w and only got excuses. I guess I'm one of the pools where they dropped the ball. They're history, too many other good pool companies out there.
