Thank you for the warm welcoming. It's about a month ago that I decided to rely on myself to service my pool after a bad experience last year at the pool store. I started reading on internet to learn as much as I could when I got caught by this forum like a gift from heaven. I immediately was appealed by the philosophy of TFP. I had no knowledge of testing whatsoever so I ordered the Taylor k-2006 that I got 2 days ago. I have not edited my signature yet but I will do it eventually. At this point I just wanted to say how happy I am to have discovered this forum and thank you for your generosity. I have no experience on forums so I need to learn that too and English is a second language for me.
