Hi to all of you guys. After lurking on this site for about a month i joined after signing with a PB. Now in the process of moving walkways,patio stones,fences, cutting trees and etc. so they can get to my backyard. The infomation i found on this site has already helped me with which PB i used and hope to use this site to keep my pool running clean and clear. Just wanted to say thanks to all of you who post so much helpful infomation.
