I picked up 2 gallons of 10% liquid chlorine at the hardware store last week. I added 100ml of liquid to my 500G hot tub and it raised the FC by about 3, where poolmath said it should have raised it by about 5.
It’s KemTek with a date code of 2121013:15C, so the 210th day of 2021. Today is the 291st day of the year so it’s almost 3 month old. I’m in the Sacramento CA area so outside temps were routinely over 100F between those dates. The chlorine was in the garden center (outside), but in an area that is shaded, plus the cardboard outer packaging kept the direct sunlight off the liquid. No idea what the storage was like before it was brought to the garden center, but I would assume a hot warehouse at best.
My questions are:
1) Is the strength loss about what I should expect for 3 month old 10% that may have been sitting above 80F the whole time?
2) Is there any problem with just using this, but needing to use more since it’s basically 6% bleach now?
3) Am I better off if I use fresher gallons of household bleach (6%)? Assuming I can find plain bleach without any chloromax additives.
Thanks.
