Containers in service guys trucks

[SDpool]

I need to store some bulk chems and always see the big blue containers in back of pool guys' trucks.
What are they? Where can I get a couple?

They usually contain chlorine or other reactive chemicals that are sold in bulk, most often 100lbs.

What chemicals will you store - the chlorine residue or smell may be harmful to the chemicals you will use.
