New here. My total alkalinity is 207 and ph is 7.7. I need to significantly lower alkalinity without decreasing ph too much. Looking for advice. I added dry acid and it brought alkalinity down from 280 to 207. It dropped ph very low. Added soda ash and it increased ph but also alkalinity.

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.

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...

You need a proper test kit.
Test Kits
You probably don't need a dedicated effort to lower TA. Just add MA to manage pH and let the TA come down with each MA addition.
Don't use dry acid. Use muriatic acid instead.
Keep your pH in the 7s.
You shouldn't have. pH will naturally rise, especially with low pH and high TA. Under normal circumstances, you should never need to add soda ash or baking soda.
Thank you for your help! I will order test kit and only add muratic acid.
