Over my pay grade too, I have only used Tri-chlor pucks. If it were me, assuming that my levels were right on everything else, I would put 2 pucks in a floater and deal with it when I got back.
Is it TFP approved? nope
Life is funny sometimes you can control things and sometimes you can't.
If you knew what your pool needed on an every other day basis and could set 2-3 jugs out and have them pour that in that would be ideal. I was fortunate enough to have that when we were out of town last year for 10 days.
If I could not have done that, 2 pucks in the floater and I would deal with it when I returned.
A TFP balanced pool you will find is so good and balanced that it can take a lot more neglect than what we are used to.
In My Opinion, that is because for me personally, my pool was always 1-2 steps away from disaster (cloudy or worse).
Now my TFP pool is 40 steps from disaster. So to recover/work with a slight bump in CYA until I splash out/ backwash out and overall adjust from it is not hard to adapt to, because TFP gave me//all of us the information that keeps things in harmony.
Again, my suggestion is in NO WAY TFP APPROVED, but I would do it and bet a donut that I would not have to SLAM when I returned.
I have lived with a horrible pool (self inflicted yes), I know what I threw at it, unfortunately my memory is very good.
I also lived with a TFP pool last year and I tested my luck, take a perfect pool and ignore it for 5 days, test it, what adjustments needed to be made? Bump Chlorine, vac, looks great, tests great again. Can my pool last 5 days without me, yep.
Once you know how to fix something, you have a better understanding of the difference between a break and a scratch.
BTW, take pics of before and after and test results.
