Hi you all,
I am now questioning the pH in my spa. While I thought I would see this climb, like in the pool, it usually falls. I use the 3 step bromine system as outlined at this site. It was today that I did some reading and learned that the bromine tabs I keep in the floater are relatively acidic and will lead to a drop in the pH. I keep the water temp at approx 100. Here are the latest levels:
Br 10+
pH 7.1 (hard to decipher today. The color was slightly orange, slightly pink. I could not tell if it that was the color after 7.2 or leading to 7.2)
CH 150
TA 70
Now, I am not sure what to do to stablize the pH. I was thinking the TA of 70 wa keeping things stable, but I guess it has not been. I don't think I can get accurate tests w/ the pH tomorrow AM b/c I just shocked it this AM and that shoots the Br and pH way up. Once the Br falls to 10 or less, can I then get the pH level and assume it is relatively accurate?
Should I add baking soda to bring up the TA slightly? If I raise the TA to 80, will that help or make any difference?
Do I add soda ash or washing soda to bring the pH up? I was trying to look around the forum a little, and I didn't see this being done in spas.
Am I supposed to aerate instead of the soda ash or washing soda to bring up the pH?
Confused on how to proceed. Appreciate any help. Tx.
