TA not going down much

[ramirez41]

Am I understanding something wrong? I am trying to get my TA down and it doesn't move very much. Here are my 2 tests from today and what I added.

Your TA moved about what would be expected…

Looks about right.

It's a process, not a one time thing.

Lower Total Alkalinity

A lower Total Alkalinity level can help a pool owner stabalize their pH increase. We'll explain how to lower TA with a little help from muriatic acid.

What makes TA go up? I had it down to 120 at one point this season. I have only used liquid chlorine and acid this year. The liquid chlorine is from the pool store. The brand is online pool shock 12.5%

Adding higher TA fill water.

What is the pH, TA, and CH of your fill water?

What is the pH, TA, and CH of your fill water?

I have never tested that. I do run our hose through a filter. I need a new filter though because I am past what it claims to filter from doing a partial drain to lower the cya.

I was wrong on my lowest TA for this summer. It was 110 after we did the partial drain. We have not added anymore water since then, but we did have some rain.

Rain has a TA near 0.

Check the fill water TA.

 

[ramirez41]

Fill water came back as
TA 220
PH is 8 or higher
CH 20

From reading the article again I need to mainly just focus on keeping my ph in the proper range. I don't have any scaling issues and never have. Not sure if my ph is rising too quickly or not since this is my first year using this method and I do not know what is normal with this method. In past years I only had to adjust my ph maybe once at the beginning of the season and it wasn't much. My ph has been 7.8-8 for a couple weeks until today when we purposely dropped it. Looks like the pool store had my TA at 85-88 last year.

Pool Stores do an adjusted TA that makes your TA look lower then it really is.

Do not compare Pool Store methods with TFP methods. It will just confuse you.
