I've been having a problem with ph rise recently, and did some research and determined I need to drop TA. It was around 100 ppm.
I added dry acid, aerate, and continue until my ph stopped drifting above 8. I finally got it to sit around 7.8 and now my TA is 50 ppm.
I've read that low TA is bad for spa components like the pump and heater, is it true? And spa surface? What about sanitizer effectiveness?
My spa is 500 gal, using dichlor/bleach sanitizer, ozone generator.
