Looking at the "hole in the ground" in a new way after finding this site. Great information! Only wish I had found it sooner. Just received my Taylor K-2006 test kit and slamming the pool now! Our house had the pool when I purchased it in 2005, had a new liner installed in 2009 and have just been tired of the upkeep the last few years. Now I'm psyched! Have to get the pool clear, fix a leaking light and I'm good to go knowing this site is here! Now if I can just find a way to hide the nosy neighbor's house behind me since he cut all the large trees down. Less leaves, but not so nice view!
