Just recently retired and decided to have a pool installed. Had a Intex pool several years ago just long enough to realize what a pain they can be. Luckily, I found this site this time and now have plenty of time to learn from you guys and try to do it right. Pool has been up and running four about a week following start up instructions from pool dealer. I’m looking forward to getting away from pool store instructions and doing it the TFP way. I bought the TF-100 test kit, should be here today or tomorrow. I will definitely be posting results and looking for help. I’ve already read your pool school several times and looking forward to getting started! Thanks for a great site for help and information!!!
