Does pH play into the BGT in any way? I've been successfully running my pool with low CYA (~30ppm) pH (~7.2) and chlorine (~1.5ppm). But after adjusting the alkalinity in an attempt to reduce acid use, the pool still 'insists' on settling at 7.6 pH when I don't add acid each day. Which, if I leave it there, makes me think I may want to bump up the chlorine to adjust for the effect of the higher pH.
