Yesterday we had a nice sunny warm day and I decided to do an experiment. My test results before the experiment were; FC - 7.5 (we had company over the night before and added extra liquid chlorine. This reading was expected) CC < 0.5 pH - 7.7 TA - 60 CH - 170 CYA ~ 30 (pool store tested at...

Great info! Thanks. As for the MA addition, it sure doesn't take much to impact things. As it stands now; FC - 3 CC - 0 pH - 7.6 TA - 50 CH - 170 CYA ~ 30 Borates ~ 40

Thanks for the feedback! I will trust my Taylor test numbers. It just seems weird that the dealer test is so "off" on the pH and TA. Any thoughts on why this might be? For a party...given CYA 30, would a FC of 8-10 ppm seem reasonable as a starting point? If so, guidelines I've read for...

We've had our Arctic Ocean series 5,500L swim spa for almost a year. During this time, I've learned alot about water care for hot tubs, and enough to realize that using the TFPC method is how I want to maintain the water. We run our unit year round, live in Canada and during the winter months...
