Recent new member, my first post. I recently inhereted pool maintenace duties for my mother and I am grateful to the TFP forum for a quick learning curve. I have two questions that I haven't found directly addressed in the archive or stickies.
(1) I have both Taylor 2005 and LaMotte Pro-7 colorimeter test kits. I like the Pro-7 for FC and PH. I like the Taylor for ALK and CH titrations, and it's nice to have a double check. Would TPFers place confidence in home tests or the PS's when test results disagree (assuming no bad chemicals or testing technique on the TPFer end). Does the PS have a superior test "lab"? There are three stores in my area, and they don't get the same results. Sometimes off as much 100% with CYA, CH and ALK using the same sample.
(2) And secondly, to correct or not to correct TA for CYA? Taylor says yes, but notes that "some members of the pool/spa industry question its value." Not that important at high TA, but I am keeping my TA at 65 and my PH stays dead-on at 7.5/7.6 for weeks. I really like that. At a CYA of 45, is my TA of 65 really only about 50 ppm?

The forum here has made maintenance so understandable (and affordable), I feel like I'm overlooking something.
