Lowering TA

[stevo777]

The general forum advice to lower TA is to lower pH to around 7.2 by adding muriatic acid, and then letting pH drift up through aeration or other means.

However, I have not been able to get TA below around 120. pH drifts up fairly quickly due to the SWCG (probably exacerbated by the high TA) and aside from the spa jets, there are no water features to aerate the pool. I am just trying to get a better TA balance to reduce the amount of acid I need to add each week.

Instead of letting pH drift up due to SWCG operation, am I better off turning off the SWCG and forcing additional aeration independently while trying to adjust TA?

Fill water with a moderately high TA is probably contributing to the problem, here in the desert southwest.

@mknauss mentioned in a different thread that he lowers his pH to 7.2 twice a week to help keep his TA at a reasonable level.

Dry Skin caused by Low FC and High PH?

Ok...long story short, I have been doing TFP method for about 2 years now:). One thing I noticed after implementing the TFP method is how "clean" the water feels and how good my skin feels when I get out of the pool For the first time this week, I noticed my skin is EXTREMELY dry/chalky after I...

SWG has 0 to minimal impact on pH rise. Your TA is the cause of the rise. Your Evap rate and water replacement with high TA is what you are fighting.

Lowering Total Alkalinity (TA) Quickly with the Acid Aeration Method

Thought I'd make a post that might help others. We've had quite a few members this year with high TA, and I've been typing the same information over and over. I'm going to post this so I can link it to help others. High TA can cause rapid pH rise. High TA is typically caused by high TA fill...

I do. With a fill water TA of 130 ppm and water evaporation right at 2% of pool volume per day from May thru September, it takes a lot of acid to counteract that fill water.
