An update on the storage.
Not so much where it was at when it went in the fridge, vs. where it's at now.
I have no way of knowing that, as my pool wasn't up yet, so I couldn't test it in a known decently sized volume of water. Although I did think about doing it in the bathtub, haha!
Finally dosed the pool with this 10% HTH Liquid CL and BOOOOOOYYY is it WEAK!!
We're not talking at 1/2, no, nearly half of half.
It's at about 3.35%.
Here's what I did.
Filled my pool by tracking the water meter counter and subtracting for toilet flushes during that time. No other water was used and I rounded up our 1.6gal/flush toilets to acct. for hand washing afterward. This was only about 0.4 extra gallons, good enough.
So I got 3320 gal for the pool after rounding down to the nearest 10s of gal.
It's a 3284 gal rated pool, so that sounds good to me since I fill it a bit high.
The 1st addition and testing of CL after dark, while adding CYA post initial fill, showed an extremely weak concentration. I didn't write the numbers down, but recall them being close to today's, between about 3-3.35% concentration. Around a 1ppm-1.5ppm actual rise in CL when it should have been 3.5ppm-4ppm. It was as accurate as I could measure using a 2 cup glass Pyrex that has proven very accurate over the years.
To get it up to its initial full dose for my CYA, I used store bleach the following morning, had to buy some, until today when the CL had dropped enough to dose again.
I added 182.5 ml of the 10% liquid CL which should have raised it 1.5ppm.
I chose this odd number as it was spot on for 1.5ppm, right at the flip point from 1.4ppm on pool calc. Plus, I only have so many measuring spoons and the like. *grins*
Needless to say, testing 30min. later at dusk, it only raised it 0.5ppm!!!
I'll add that my CL loss has been
THAT daily! Due to fire stricken skies resulting in rather low UV. So it wasn't a UV loss issue in that brief 30min. time.
I did the math on Pool Calc and got 3.35% liquid CL concentration.
YIIIIKEEEESSS!!!
That's a 66.5% reduction in concentration over the rated amount of the product. Seeing as it has been in my garage fridge since May, when I bought it. How old is this stuff? Mind you, this is Oregon, it doesn't get ragin' hot here and when it does for our "raging hot", it's not for long. So assuming it sat in the warehouse (OR, WA, NV, CA??), then in the store, in a non-refer truck and maybe on the dock for a bit. This stuff must be well over a year old, maybe close to 2-yrs old?
What do you think on age?
I tried calling HTH Chem..... no luck! Called them from the store, when I bought it. The flunkies had no clue what a lot number is or what to do with it. It's: "their number on the bottle" that doesn't exist, or bust! In fact, they don't even recognize their packaging; clear milk jug type bottle /w a yellow cap, in a cardboard box, 2 per box and a lot number on the box. Duuuhhh, we don't sell it that way they say. UUUGH! RIIIIGHHT!!
So I'll have to call Arch Chemicals and go through their maze of phone numbers to find someone who knows what this lot number translates to.
But something tells me I'll still end up coming out empty handed in that adventure.
EDIT: I should add that the 10% liquid CL is still very yellow, much more so than the std. 8.25% I'm used to. If this means anything, or not.
