Can't express how happy I am I found this site. As a brand new IG pool owner, I was worried about being able to balance the water myself and keep the pool looking great. The PB finished about 2 weeks ago and I figured that the water was balanced. I bought the Taylor 2006C kit and found that my chlorine level was almost non existent with no CYA. Needless to say the little chlorine that was in there was gone in a matter of no time because the SWG wasn't set properly and no CYA. With the great test kit that was recommended on here as well as the recommended levels, I was able to get the water balanced properly. Thanks to everyone who contributes on here.
