Even worse - 18 days it was 260!..If your fill water has a TA of 60 how is your pool TA getting to 160? And you say it has risen from 110 to 160?
Have you added any alkalinity increaser, baking soda, borax, soda ash or washing soda to the pool?

A couple of months ago, I bought Muriatic acid, thinking it was the same as CYA... I had my ignorance corrected on this forum - but by then, the pH was 6.2. I fixed the pH with 6 lbs sodium Bicarb (Arm & Hammer). Could that be the problem?
Okay, I'll make a quick correction, with apologies here... I used Arm & Hammer washing soda - 100 % Sodium bicarbonate - 12 lbs of it, not 6 lbs, but 12 lbs.
Thanks!That is a much bigger effect. About 130 ppm TA and 4 points of pH. In the future, never add that much of any chemical at once. And preferably never use soda ash. It is taking a sledge hammer to the issue.
Regardless. Keep your pH in the 7's. The TA will fall. Or follow the process to lower your TA in TA - Further Reading
Good question. I've wondered about Arm & Hammer "Baking Soda". On their website, it's listed under "industrial". According to them, it's sodium bicarbonate.
