Local janitorial supply store - 55 gal drum of 12% for $150

I'm looking for some insight from anyone who has done it this way.

I've got a good storage area for it right next to the pool.

Its a good idea! BUT.....doing the numbers:

Walmart 6% bleach is $1.67/gallon. $1.67*55 = $92.00. Double it (for 12%) and you get $184.00.

So you would be saving $34.00, but having to store 55 gallons somewhere (all at once, instead of buying it when you need it), and also need to factor in the fact that 12% turns to 10%, 9%, etc. faster than 6% turns to 5%, etc.

Every year I try to think of a better way, and every year I just end up buying jugs from Walmart.....usually enough to cover 2 weeks at a time, just to save trips. Oddly enough, this year bleach hasnt gone up in price from last year and the container size didnt change (like they would do to "sneak in" a price increase without actually increasing the price)

But it's also 55 plastic jugs that don't go into the waste/recycling stream.

If you could find a few other folks to share, you could get around the deterioration issue. If it's a standard 55gallon barrel, it will accept a spigot so you could fill empty bleach jugs.

IF the pool stores in your area sell 10 or 12.5% chlorine in refillable carboys that is often the best deal, better than bleach much of the time. Check the prices. For example, we sell a 2.5 gallon carboy for $3.99 with a one time purchase price on the carboy of $5.99. After that every refill is $3.99. That is the equivalent of 5 gallons of ultra bleach, which costs more than $4! (Plus you don't have empty jugs to throw away.)

Thanks for the info gentlemen.

Option number 3 -

Found a 50 pound bag of "Dry Bleach" by franklin technologies for $47.00

MSDS says:
*Sodium chloride - > 50%
*Sodium carbonate - >30%
*Sodium percarbonate - >10%

Can anyone interpret this for me?

MSDS is here:
