Cheap bleach for those in the midwest.

Thanks for the tip! I'm getting tired of the 6% bleach from Aldi's only being about half strength despite having an expiry date 5 months away. I'm heading to Menards today!

If they are out, or you want to buymore than they have, get a raincheck which they call a Sorry Slip.the raincheck lasts for 90 days and you can use part at a time if they do not have the full amount. My raincheck is for 50 gal.my store only carries 42 a a time. I'm hoping to spread thi price out over the next 90 days by buying 12 or so at a time.

And now this week they have 15% one gallon LC for $2.50...

The label on these at Menards says 15% available chlorine and 12.5% sodium hypochlorite. I'm assuming that means it's 12.5% concentration for our PPM calculations. I'm not sure what the available chlorine part means but maybe somebody can explain.

I used the Menards Pool Chlorine a couple of days this week and a strange thing happened: I had some brownish colored foam in my skimmer basket the next morning... weird.

Bucket test gave me approximately 14.5%. The sale ends today Btw.

I went to Menard's this evening to buy some of this stuff and I couldn't find it. What section is it in? I looked near laundry detergent and pool supplies. I found some "outdoor bleach cleaner" with the cleaning supplies, but I couldn't find anything on the label that said what the chlorine content was, or what other ingredients were in it, so I decided not to take a chance on it.

It was near all of the pool supplies at our Menards... It's labeled "Clear Extreme Pool Shock" (white and blue label) Look for the bottle of neon yellow colored liquid.

I bought some of it and did a bucket test and mine showed 10%. I wish somebody could explain the 15% available chlorine and 12.5% sodium hypochlorite. I really think the 12.5% number is the one it's supposed to be. I'm confused by your 14.5% result since I think 12.5% should be the highest you should get. I could be wrong though....it's happened before...lol.

I believe the difference in the label of 15% available chlorine and 12.5% sodium hypochlorite may be difference in units - weight vs concentration.
The difference in test results has to do with freshness. Bleach (sodium hypochlorite solution) degrades very quickly when exposed to warm temperatures and sunlight. The manufacturer / packager bottles it at a higher concentration than the label in the hopes of still having the label concentration when it gets to the store.

The stuff I bought was still in the 4 pack cardboard carrier. There were several loose bottles floating around the display but since chlorine can degrade under sunlight I opted for those in the boxes. Mine had manufacturers date stamps of June 2012, so they were relatively fresh.
