Interesting observation about bleach tonight

[mynewpool]

I was at my local HEB and went to the bleach aisle and it was empty or at least I thought it was. I went down the aisle and it looks like they got rid of the 6% bleach and is being replaced with 8.25% bleach. This included clorox brand and the HEB brand. On the container it said now concentrated and of course the smaller quanity equals more than the old 6%. They had the smell ones, but of course I got just the regular bleach. So not sure if this is something new for Clorox or what, but just wanted to give a heads up. It was 1.99 for 64 ounces. Not sure if that was a good deal or not but I needed bleach.

Thanks.

Yep its official. I'm not sure what the "real" reason is for going to a higher strength but if I was a bettin' man it's all about the $$$$. Lighter = cheaper for all those handling it. Trucking, warehouse etc.

New Clorox MSDS

Old Clorox MSDS

Note the Sodium Hypochlorite % range change.

It's all about the shipping. It costs a lot to ship water. :-D

As a side note; The new stuff is made with a new process that strips a lot of the salt and lye out of it. That makes the shelf life a lot longer.

Is there any plus or minus in terms of managing a pool (besides cost and/or treatment amounts?)

 

[Bama Rambler]

No, you just adjust the strength in the pool calc to account for it. It probably won't build up salt as fast but that's probably not something you're going to notice anyway.

I'm not sure how they figure this is more. The way I figure it: 64oz at 8.25% is 92% as much sodium hypochlorite as 96oz of 6%. Put another way - I used the Chlorine Cost Spreadsheet to normalize both a 96oz jug at 1.99 (my local generic 6% at Food Lion) to the 64oz 8.25% and comparing the cost of each expressed in 6% strength gallons:

6% 96oz @ $1.99 = $2.65/gallon of 6%
8.25% 64oz @ $1.99 = $2.89/gallon of 6%

It says the 64 ounces is equivalent to 96 ounces at the lower strength.

On the pool calculator you can just put in 8.25 instead of 6.

As UWV shows, it is not the equivalent amount of HCL ... almost 10% less. Cheaper for them to ship. And you are getting less product for the same cost.

Could be nice if they put it is 182oz jugs though ... less to carry.

Target also is going this route with their store brand. They had all their large 182oz jugs on clearance for $2 on and endcap right across from the new concentrated 8.25% so of course I snatched up all they had for that price.

For laundry it may be the same number of loads but only if the reduced the amount of oxidizing power per load.

Math does not lie. Advertisers, labels, etc do.

 

[mynewpool]

Well all I know for my purpose I get to use less bleach when adding due to the higher concentration.

But for the same FC ppm rise, it now costs you about 10% more $. {Assuming the price is the same for the small bottle}

The way i learned it was

Figures don't lie, but liars figure.

This is especially important to remember in an election year.

i just saw the new "big" bottles of this 8.25% bleach at sams club (121 oz). they claim 121 oz of 8.25% is the same as 182 oz of 6%. can yall figure if this is a lie too? i don't know how. thanks

 

[UnderWaterVanya]

The 182 oz jug at the same price would be a better deal.

Here's one way to do the math:

182 oz * 6% = 182 * 0.06 = 10.92 units of bleach
121 oz * 8.25% = 121 * 0.825 = 9.98 units of bleach
% = partial / total , so 9.98 / 10.92 = 0.91 = 91%

I rounded off some of the numbers, but they don't change the analysis. For pools you aren't getting as good of a deal as before if prices remain constant.

 

[brg88tx]

so we're getting around a 9-10% screwing with this "new and improved" bleach

Yes - although my suspicion is that prices may drift up or down from the current pricing as competition tests the waters. In theory if the process isn't more expensive the ultimate cost should go down since they can pack more per truck/train etc.

I bought some of this concentrated bleach today. My bottle is 121 oz. The pool calculator has a spot to specify 8.25%, however, it does not allow for the new 121 ounce bottle. The bottle says "the old 182 @6%=the new 121 ounces @8.25%. based on this, do I 'pretend that is is 182 ounces of 6%?

 

[Swampwoman]

The pool calculator will tell you how many ounces you need anyway, so just use the number of ounces it comes up with at 8.25%.
I just switched to 10% and that works fine.
