Even under no load, ozone will just barely "keep up" with natural sanitizer decay in a clean spa. Mine won't go above 1ppm. If left alone, 30ppm will naturally decay asymptotically over a few days (meaning it gets close but won't get to zero). Its a great vacation plan! Yes sodium hypo is net pH positive. Thanks! Being net positive then are you finding you have to add PH down regularly to compensate? Quote Link to comment Share on other sites More sharing options...
