Menard's Liquid Chlorine

[sbn56]

So Menard's in the Midwest had liquid chlorine for $2.50 a gallon, that fact has been well-broadcast hereabouts -

On the bottle, it states 12.5% sodium hypo, but 15% available chlorine.

I've been dosing with this product assuming it's 12.5%, just to be on the safe side.

Can anyone speak to the difference in numbers, or is that to be expected? Having just jumped to the BBB method, I have never read the label on any other liquid chlorine.

Great forum! It will be even better when someone comes up with a better method to deal with liner wrinkles! Never again. Never will I EVER try to do my own liner, especially when a cold front comes in 12 hours early and we're trying to finish in rain and 55 degrees. And the resulting bottom shows it..........

thanks!

So I had another few free minutes and went over to read that this has already been posted and answered!

Another waste of precious electrons...........

Hi sbn56,
I use Pinch A Penny liquid chlorine that's rated at 10.5%.
In my additions I found I need to add in the calculator for 10 % for the numbers to work spot on, not the extra 1/2 %.

That's ok. Yes, the "available chlorine" is not really useful information. 12.5% sodium hypochlorite is simply 12.5%. May be less though depending on how long it has been sitting on the shelf.

That's why I didn't buy more than four cases.

I could not find the 12.5% at Menards. What brand is it? They had Hi Lex Outdoor but I could not see the concentration listed anywhere.

Thanks Jim

They have a very small pool section, and that's where it'll be. The Menard's near me keeps it in near the hardware section, not far from their seasonal stuff.

If you're still interested, this is what they carry at my Menards.

Their bottle (referring to the numbers sbn56 posted) is labeled incorrectly. % Available Chlorine (weight % of chlorine) < weight % of sodium hypochlorite < Trade % (volume % of chlorine)
Chlorinating liquid is usually quoted by Trade % which is the volume % of chlorine so is what you could use to readily calculate its effect -- 1 gallon in 10,000 gallons will raise the FC by the Trade %. It's possible that they meant 12.5% Available Chlorine and 15% Trade % or the 15% number may just be bogus.

Had to revisit this thread to check on 15% being 12.5%. As I thought the consensus is that it's 12.5% as listed as the ingredient, not the 15% listed as "Available Chlorine."

Farm and home has this same "shock," on sale for $2.99/gal.
