Chem Storage

[JamesHayhurst 14]

I've decided to start buying sodium hpyochlorite in bulk but I don't know the proper procedure for storage. Can anyone help?

You want to keep it cool and out of the sunlight.

How cool?

Does anyone know the decomposition rate of 12% sodium hypochlorite?

here's a helpful link:

Thanks for the link!

How do you know if your bleach is filtered or not? That seems to make a huge difference!

Filtered bleach is used in industry. Most bleach from pool suppliers is NOT filtered....so it has been explained to me by my local supplier anyway.

Which is likely why they pay $1.00 a gallon at a pool store and we pay$2.00-3.00 a gallon from industrial chemical suppliers in the rest of the country.

I know it cleans just as good but ours is likely a little better grade (no suspended solids?)The guys in Florida use it so fast most suppliers never see degradation as an issue anyway.

That was a very interesting link.Thanks!!

Yeah, I thought it was a neat link too. I was a couple hours into a net search one day when i found it. I was looking for a reasonable, in the field, way to test the strength of sodium hypochlorite. Obviously a pool test kit is not helpful, and lab quality procedures are not necessary. If anyone knows how to do this, please feel free to share. Thank you.

A simple test is to put your finger in it. If it is warm to the touch, it's active. If it feels like water temperature, it's dead. The normal shelf life for Sodium is 60 to 90 days.
