Ok, the moment we have been waiting for:
FC - 55 (5 ml - 55 drops)
CC - 0
ph - 7.8 (Cl Br was too high and had floaties)
TA - 170
CH - 500
CYA - 40
Salt - 3200

Nothing to do but wait for the FC to come down. Not great on the vinyl liner, but what is done is done.

Nothing to do for the moment. Leave the pool outdoor in the sunlight to allow FC to come down.
Stop using the CLBR test. Just use the drop test.

Lastly, don’t worry about the pH which is not valid with FC > 10.
Ok. Chlorinator has been turned off and I'll leave the pool cover open until we go to bed tonight

You can, but it’s going to be quite some time for that to drop. No sense testing pH either.
Its going to take a week or more to come down. Maybe 3 in Minnesota because its still early in the season for you. Save your reagents and test every couple of days.
I can't believe I went from 0 chlorine to 55 ppm. 4 lbs of shock and 4 gallons of liquid chlorine over the course of a week. Plus my chlorinator running normally (though 24-7). I'll get my pump back on its normal schedule.
Don't trust me, but here's a thread about using either Sodium Thiosulfate or Peroxide to lower the CL level pretty quickly. Lower chlorine level with Sodium Sulfite
In my bad tablet days, when I was way over dosed on CL, I used Sodium T. a few times. It always was far more effective than the bottle said, and brought my CL crashing to 0. So then I had to bring it back up....
Do some more searching for threads about both, and form you own conclusion about whether to try one, the other, or just wait it out....
This week in Minn., the weather for degrading CL has been great. Not so much by the weekend when the cold front moves in.

No need. Here is your answer:
4 pounds of cal-hypo will add 15-20 ppm FC, depending on strength.
4 gallons of 10% will add 22 ppm FC.
Not sure which T-cell you have, but even the T-cell 3 can produce 9 ppm FC per day in an 18,000 gallon pool.
So 55 ppm is well within the realm of possibility.
Good to know. ChatGPT says it will be safe my next Monday/Tues given all the variables. Not great swimming weather in the 10 day forecast anyway.
Swimming is safe between min FC and SLAM for your CYA level. (2 - 16 FC @40 CYA )
The good news is chlorine burns off as a % of the CYA, so the much higher #s drop more per day.
Solely as an example : lets use 10%
10% of 55 is 5.5
10% of 5 is 0.5.
Its still going to take a while at 55 though. Report back when you test because it will be neat to see.

While you wait for fc to fall keep doing all the other things like keeping the filter running, backwashing when psi increases by 25% over clean psi,
and vacuuming or brushing the pool each day. Cover off, cell off.

Please don’t ever trust ChatGPT with pool advice. It gets all its data from the Internet.
But wait...we're getting all our data from the Internet (here) too!
I just asked it to estimate when the pool would be back to ~10 ppm. Gave it my test results and the 10 day forecast. I'll be interested to see how it all pans out.
The algorithm works by assuming the largest number of internet posts that agree on a subject is what’s “true”. The problem with that is there’s a very large number of pool forum, reddit posts, etc that fill up in the internet with questionable and bad advice. Quantity of knowledge doesn’t equal accuracy of knowledge. Enjoy the experiment, just don’t rely on it for anything.
