Tom Fitz Posted March 2, 2023 Report Share Posted March 2, 2023 I’m new to well water. I just filled my hot tub and my ph level is good at 7.6 the problem is my TA is at 220 ppm. I’m using chlorine in the tub. How can I lower the TA with lowering the ph to much. thanks Quote Link to comment Share on other sites More sharing options...
dashmer Posted March 2, 2023 Report Share Posted March 2, 2023 The stickies at the top of this forum describe the process for lowering TA without dropping pH. In a nutshell, acid to lower both, aeration to raise pH. Quote Link to comment Share on other sites More sharing options...
Tom Fitz Posted March 2, 2023 Author Report Share Posted March 2, 2023 Ph decrease the same or Will acid work better? Also could I aerate using an air compressor? I don’t have a blower on my tub. Quote Link to comment Share on other sites More sharing options...
dashmer Posted March 2, 2023 Report Share Posted March 2, 2023 pH decreaser or minus are dry acid so that will work...easier to deal with than the liquid stuff. Does your tub have air injectors with the massage jets? If so that is all you need. It is just to breakup the surface to permit exchange of gasses. PS...I also fill from a well but my well water is low in TA, pH and CH...need to increase all when I fill. Quote Link to comment Share on other sites More sharing options...
Tom Fitz Posted March 2, 2023 Author Report Share Posted March 2, 2023 I have 2 air knobs 1 for each 1/2 of the tub that inject air thru the jets. My local spy store is telling me to up the pH high and then use pH drop. To drop both of them because they said the PH increaser will not raise the alkalinity as much as the pH, but they will drop the same together. Does that make any sense?

dashmer Posted March 2, 2023 Report Share Posted March 2, 2023 Yes, that is the same setup as mine. To aerate just run your jets on high with those air knobs fully open. I think your local guy is going to send you off on the pH and TA roller coaster. I would follow the direction in the sticky if I were in your situation.
