Robelle Winterizer - What's in it?

[MITBeta]

Hi Everyone,

I'm trying to help a friend out with love closing her pool and she just told me that she got pool stored and poured Robelle Winterizer into her pool. Anyone know what's in it? I can't seem to find any details.

Looks like a flocculant and that's it...

Seems like it must be more than that, especially since it doesn't suggest vacuuming as part of the directions? Why wouldn't they just call it flocculant instead of winterizer?
