    Where do you get muriatic acid?

    Alkalinity and pH issues

    So I am following your advice and working on getting the pH down ... it does seem to be dropping, it's holding under 8 (from 7.6-7.8) but does still want to creep up. Is the 7.6-7.8 range good enough, or should I try to get it to be stable at 7.6?

    Alkalinity and pH issues

    I don't have a circ pump so the spa uses one set of jets to circulate the water. The aerators on that are always off when I get out. The manual actually suggested leaving the aerator on the other set on. This set is run automatically, periodically, to keep the pumps primed or something. I...

    Alkalinity and pH issues

    For some reason I stopped getting notifications of replies so I missed this. Yes, this makes total sense. Thanks for the explanation! I have been frustrated trying to lower my pH because it has been so stubbornly high. Do I just need to keep banging away at it - will it eventually come down...

    Alkalinity and pH issues

    Argh. So many different recommendations. The how to at the top of the spa forum suggests a TA of 50. The folks at SmarterSpa suggest 100. Now you are saying it doesn't matter. How is a person supposed to know what to do?

    Alkalinity and pH issues

    My tap water has a TA of 30-40. It would make sense to me that as the H2O evaporate is would leave the solids behind and then as I add more tap water the TA would rise. Yes or no? Re just managing pH, I've struggled w/this as it has been stubbornly high (8 and higher) and I didn't want to add...

    Alkalinity and pH issues

    Just tried again but didn't realize about the not squeezing .... did wipe the tip each time and the drops looked bigger than before. Got a reading of a solid 90. I feel like my numbers are pretty good now - added 2 tbsp of pH decreaser yesterday (1 at a time, giving it multiple hours to...

    Alkalinity and pH issues

    Re/the test, I confess I haven't followed the direction of wiping the dropper. I will try the test again doing this. And no, I haven't added any stabilizer.

    That is how it is leaving. Thanks, good to have that mystery solved!

    Alkalinity and pH issues

    I do add water, about once a month ... the tub seems to loose about an inch a month. I hadn't thought of that but that would change the chemistry over time wouldn't it? I have tried adding a little bit of pH down but not much ... it didn't seem to have a lasting effect, and since I thought the...

    Alkalinity and pH issues

    Back at the beginning of November 2019 I filled my spa and tested the TA at 40 so I didn't mess w/it. I brought the hardness up to 175 and I have an SWG for chlorine generation so I didn't do anything for FC. I have had ongoing issues w/high pH - started at 8 and has been creeping up to where...

    Can't get pH under 8 ... what's going on? do I care?

    Cool, glad to hear it, based on my experiments so far it just doesn't seem possible to get it to stay under 8. But at this TA it holds 8 very consistently so I am going to call it good!

    Filter cleaning and replacement routine

    That all makes sense, and as you, it depends on a lot of factors. My bather load is relatively light, mostly just me, 15-20 minutes/day. I suppose a lot of it is user preference ... since the discolored filters are bothering me and since I got a years worth of use out of 'em I should just...

    Filter cleaning and replacement routine

    Ah, got it. Yes, my tub has three ports at the bottom that don't go thru any filters. I have wondered how the filtering can be effective given this.

    Filter cleaning and replacement routine

    So are you still rinsing the new filter monthly? Have you used any kind of cleaning routine other than that? Fundamentally my questions come down to this: 1) How often should I replace my filters? 2) How often should I rinse my filters while they are in use? 3) Do I need to bother with...
