    Chlorine, CYA, and PH levels with a heat pump

    Thanks! I wonder if the downsides of a maintaining lower cya (and corresponding FC) levels might be lessened for me by the fact that I use an opaque auto cover most days. I seem to be stable at 4.5 FC running my swg for 6.5 hours a day at 15%. Hard for me to imagine more cya taking me much lower...

    Chlorine, CYA, and PH levels with a heat pump

    Thanks! I was up to date on the basic primers in the pool school, but I spent some more times digging through the forum and found this discussion that helped me understand what's behind the recommendation to maintain SWG pools at much higher CYA levels: CYA in salt vs non-salt pools

    Thanks all, this was very helpful!

    Chlorine, CYA, and PH levels with a heat pump

    OK, that's fair. So my real question is, can I follow the TFP CYA/Chlorine guidelines without damaging my heat pump, notwithstanding what the Crosswind Manual says? Same question for PH: Will keeping PH at 7.6-7.8 damage the heat pump? EDIT: I guess your answer to both questions is yes, I...

    Chlorine, CYA, and PH levels with a heat pump

    I am about to install a Crosswind 65-I heat pump. The manual recommends FC in the range of 2-3 ppm, with a stern warning in bold in that FC MUST NOT EXCEED 5 PPM (see screenshot below): I use a SWG. TFP recommends I bring my CYA up to 70 or 80, and target an FC range of 5-10 or 6-11. This...

    Threshold of concern for dry acid added to a SWG pool?

    Thanks @ajw22! As a follow-up, I called Pentair tech support to ask my question. The Pentair technician said that I didn't need to drain or dilute my water, but advised me to increase my SWG output (say from 10% to 20%) for the next 24 hours, implying that it would remove somehow eliminate the...

    Threshold of concern for dry acid added to a SWG pool?

    Greetings all! This is my first post as a relatively new owner of a 7600 fiberglass pool (the Latham Olympia 12), with a SWG, for which construction was completed October of 2023. I am in Sacramento, California. The pool has an autocover which I've been using most of the time up to this point...
