I had to drain a bunch of my pool because of CYA of ~110 or so. Since that time I have been judicious with my use of trichlor and have instead been using bleach to sanitize. For my 14500 gallon pool I’ve been adding close to a gallon of bleach per day and that seems like a lot. Could there be other chemical issues at play?

Welcome to the forum!
What % sodium hypochlorite is the bleach you are using?
How are you testing your pool water chemistry?
I suggest you read ABC's of Pool Water Chemistry.

For reference I have 3 times the gallons and need a skootch over a gallon for 3 PPM. Something is most likely going on. The 2 above questions are the start of narrowing down the ‘what’.
Thanks for the quick help!! Was using 6.8% but now 7.55%.
my cya is ~40 and I’m using the tf-100 kit. Thanks!!!

So at 6-7% you will need about double the bleach. Factor in the Texas sun at its worst right now and it might not be too far off. Perform an Overnight Chlorine Loss Test To rule out any ickies.

10% is very easy to come by for us. Walmart pool essentials is my favorite, but lowes and home depot also carry it. Heck, my Kroger even has a small pool section with 10% HDX Liquid Chlorine.
Leslie's pool store carries 12.5% Liquid Chlorine for about $18 for 4 gals. That is mainly what I use unless I can find something cheaper. use the Pool Math app to calculate the $/oz of equivalent chlorine
