Can't get TA to drop

[Drew80]

I've gotten advice to drop my TA down a bit so I don't have to fight my pH all the time. My pH is constantly rising - I add about 5 cups of muriatic per week, give or take. My TA is currently 80 and I'm trying to drop it to around 60.

I've tried multiple times bringing my pH down to 7 and then aerating, and every time my pH comes back up as expected but the TA doesn't move. I've been sitting at 80 for weeks.

Any advice?

So right after you add acid, TA does not drop? If so, you may not be adding enough. Are you following the steps in pool school?

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.

Does your fill water have high TA? If so, you may be adding it back in when you top off the pool.

@mas985 it drops initially but rises back to the same level. It never stays down.

Then something is being added to the pool. TA only rises when something is added to the pool. What are you adding besides chlorine and water? If nothing, then it must be the fill water.

Must be my fill water. It tested at 60 a few weeks ago, but it was 350 back in 2018. Austin's water treatment must be a little wonky.
