    Ozone and PH

    Does having an ozonator and circ pump, running continually, affect PH? I'm having a hard time bringing down my PH and TA; PH=8.0 TA=200. It seems like the constant aeration would keep the PH high. This is in a hot tub, 330 gals., 99 degrees. I added what the pool calculator suggested and it didn't have any noticeable effect; am I just being a chicken not wanting to dump copious quantities of muriatic acid in my tub?

    You're being a chicken

    The aeration from an ozonator, especially if on a lot of the time, does make the outgassing worse, but running jets is even worse. At any rate, a TA of 200 ppm would even have the pH rise significantly in a pool, let alone a spa. You really need to get that TA down A LOT and yes, adding a bunch of Muriatic Acid is the way to do it, but in a spa the process is much faster because you can aerate significantly with jets. Just follow the Lower Total Alkalinity process.

    Thanks! I guess i missed that part of Pool School. I overcame my acidophobia ,followed the directions and TA is coming down. This is a great board!
