Hello! New here, but am finding this information very helpful too! It has been years since I had a tub and just got one again. It has an older genesis bromine generator on a 24/7 circ pump. Lots of jets, and I’ve been re-learning the spa chemicals. I’ve been having these same pH rise issues and that was just with trying. To maintain a TA of 80. I’m letting it all settle out and fall where it may, my TA is around 50 and still falling, but my pH has become increasingly stable. For some reason I thought the TA buffer was something other than using the carbonic acid system. All those years of physiology makes me thing of phosphoric acid, lactic acid, albumin as good buffering systems ;) I’ll be adding boric acid when it arrives to 50 ppm. Once borates are in play, do you really need to mess with the carbonic acid system as much through the use of bicarbonate? Seems like that is just a continually losing game where co2 is lost. Is there a different type of pH adjustment that can be used that doesn’t have intermediaries that are offgassed? I’d rather get it dialed in and create a strong buffered system right within the correct ranges than needing to continually correct it...
