need to cover my pool for 6 weeks while i am away...help with chemical suggestions

[PoolDoc]

Found it.

It's made by AllChem, and sold under a bunch of labels. HomeDepot has an MSDS available for it, here, under the HTH brand.
The Doheny's "Lo Chlor" label is here.
(both archived locally)

It's just a copper algaecide:
"Ingredients Found:

11.83% of COPPER SULFATE (PENTAHYDRATE) (161)
88.17% of INERT INGREDIENTS (0)"

And, no, it will not keep your pool algae free for 90 days, unless you also chlorinate, filter, and otherwise do everything necessary.

Oops. Anna, I still had this open from last night, and didn't check to see if someone else had posted. My bad.
