It’s definitely old by now (299 day is roughly late October). It’s probably closer to 8% than 10% as long as it was stored in a cool dark space. You can still use it but you probably will not get the FC increase you expect from calculations. Use it, add what you think you need and then adjust the needed amount after retesting.

I bought some of the same brand awhile back and the number was 23622. Does not fit the decoder system. Thoughts?

August 24th 2022 … wow, if you have the receipt you should return that. It’s almost 2 years past its manufacturing date. It’s probably a few % chlorine and mostly salty high pH water.
I dunno who needs to hear this, but old jugs or last years leftovers still work great for cleaning projects. I use mine to clean my vinyl siding and PVC fence each spring.
If I still have a jug after that, it gets demoted to laundry duty.

Different manufacturers use different date code formats. Even the same product can have different date code formats if they come from different plants.
