Thanks Rod, good article.

Interesting article Rod. Thanks!

The numbers show a much slower degradation than I would have expected.

I appreciate that!
I used to get my chlorine in a 300 gal tank and store it in my vacant lot.
I stopped, because I guessed that it was losing strength in the summer, when my work here in Florida is slower.
I think i'll go back to it again now that I read your info! THANKS!

That doesnt seem right. In a tank stored outside in an enclosed trailer, over 30 days it loses its cleaning proficiency. I stuck a pool strip in it and got 'no free chlorine' reading. That may be different than available chlorine but the cleaning power is markedly reduced. just touching it tells you that its lost power. If it isnt warm when you rub some between your fingers, it aint gonna clean.
thanks for the page anyway, Rod

Now that spring is almost here, how do we know if we are buying fresh SH or last years leftovers from the local pool supply store?

[Jim in NJ]

I read on the clorox site that SH degrades faster in the heat and therefor they make it stronger in the summer months. light has nothing to do with it.

Light does effect light sensitive chemicals like Sodium Hypochlorite/Bleach.
Here is some info on it http://www.plastics-etc.com/pdfs/tan...hypo_tanks.pdf
