Just want to say thanks to all that have put this site together and made the care of my pool so much easier. My results have been phenomenal using the app and the TF100 test kit. We built our pool exactly one year ago and weren’t really given any exact instructions except to keep the water balanced and handed a bottle of Aquachek7 test strips. Pool always looked ok. Now using TFP and pool looks amazing. Just wanted to put a word of thanks out there and love having all the fantastic information.
