I have a high alkalinity level in my 20X40 in ground liner pool
every thing else is normal
How do I bring the alkalinity level down without changing the other readings?
Thanks,
New pool owner

Follow the procedure in this post. The key is to strongly aerate the water at low pH and then add acid to keep the pH low and keep aerating. It takes a lot of acid, but it would take that amount of acid no matter what you did -- the aeration at low pH just speeds up the process of outgassing carbon dioxide from the pool which is how TA gets lowered. Pools are intentionally over-carbonated so you are essentially just stirring up or blowing bubbles into a carbonated beverage to make it go flat faster (and adding acid that also speeds this up -- think of what happens when you add vinegar, which is acidic, to baking soda).
