Getting TA Down

[Imracerx]

How do get my TA down?

Do I add the MA to lower the TA then use Soda Ash to raise the PH?

My current TA is 110, trying to lower it to 80.

Thank for the help.

You lower TA (and pH) with acid, then raise pH (only) with "aeration" as noted on the TFP Pool School - Lower Total Alkalinity page.

Since I don't have a spa, fountains, etc. It did mention SWG, how does that work?

Also, are you able to swim during this process since the PH will drop so much?

Just a few questions first. How bad is your pH swings? I ask because 110 is really not that higg. TA is one that you should not focus on. There are always exceptions but for the most part TA will live where you get a stable pH. How new is the finish. Plaster will cause a rise from curing for up to a year. Just manage your pH and let your TA live where it wants.

Since you generally only lower pH to 7.0, swimming is not a problem. I agree with jcowart that if your pH is stable to just leave TA alone. Only adjust TA if you have to add acid every few days to keep pH in range.

I use this to aerate..

My Ph stays steady on with a TA of 110. If your Ph is stable don't fuss with your TA. Hey jcowart, I think we have the same pool!

The plaster is older, not sure of the age. I just switched to a SWG from chlorine. But the pool school mentions to be at 80 TA and 7.6-7.8 for PH. I was trying to mirror what was recommend for a salt water pools.

My TA hasn't changed for months, I just add MA a few time a months to lower PH. Since I just switched to salt water is there anything that I should expect differently from chlorine pool? Cool Picture!
