Thanks for the quick reply. I ordered Ben's kit in June in anticpation for a June completion date....pool did not get completed until this week, but the good thing is I have the kit. I will go back to the pool solutions site and start reading. The pool company sent someone out to start up the pool and I did not like what they did....they added a lot of muratic acid (I know it needed some, but I prefer to add a little, let it adjust, test and then add some more. Whatever he did took the pool (which had just been filled the day before) from a PH of 8.2 to 6.8, alk from 120 to 40. I'm glad they are gone and I told them they don't need to come back - I will adjust my own way (with the help of Ben's kit) and some speed reading! I owned a pool several years ago and flawlessly kept it with the use of minimal chemicals (chlorine, muratic acid mostly). I followed the advice on this forum and never had a problem. It has been a few years since we moved and I feel like I forgot everything - even where to find the info on the website! Anyway, I appreciate your response!
