Spa TA and PH problems

Postby Evilgirl » Fri 27 Oct, 2006 10:59

Hi, I take care of the pool and spa where I work. They are both on a salt water system....the spa has only been on it for about 2 months.Things were fine but in the last 2 weeks the TA and Ph are so high in the spa. So I got some Muriatic Acid and carefully added it to the spa...directly... I didn't know that you were supposed to mix it with water first, and I did it 2 days (wed and Thurs) in a row and today(Friday) I add PH down in powder form. It makes things ok for a bit but the next morning the levels are high again. How long should I keep tring to get the TA down? and i read that I should wait 3 days inbetween treatments? and I will mix it with water from now on. Thanks
