Hello All, a quick question about my PH levels. I've been caring for my pool for a little over 2 months now and I'm noticing an odd trend. My PH levels seem to love to be at an 8.0 with an alkalinity of 80. I follow pool math and add Muriatic acid weekly to drive it down to the prescribed 7.5-7.8 range but after a week (with no rain) it's back up to an 8.0. I do have a small waterfall on my hot tub (hot tub is pool temp), my thought is the small bit of aeration caused by the hot tub is causing the PH to trend upwards. Does that make sense?
here are numbers from today's testing:
