It's been a few days; hopefully it's gone now. Solar UV + chlorine will clean up a bunch of things.

If it's NOT gone, I'd call Leslie's. I did find the MSDS . . . and the ingredients are NOT something I'd want in the pool:

Citric Acid - 77-92-9
Etidronic acid - 2809-21-4
Butoxyethanol - 111-76-2
Poly(Oxy-1,2-ethanediyl),.alpa.-(nonphenyl) - 9016-45-9

+ Citric acid reacts badly with chlorine and is a problem on indoor pools. It should be OK on an outdoor pool after a few days.
+ Etidronic acid is just HEDP, a metal sequestrant. It's not a problem.
+ Butoxyethanol is a apparently an unregulated carcinogen (Wikipedia). If the Wiki article is accurate, you do NOT want to swim in that stuff.
+ Poly, etc is a apparently an "ethoxylate" that's not too bad for people, but is not so good for fish. Makes me wonder about them putting in a filter cleaner that's going to be backwashed into ditches, etc. Maybe that particular product is not so toxic to aquatic life. Or, maybe there's very little present -- the MSDS didn't have percentage values.

Sorry it took so long to respond; good luck!
