Question: To keep the water barrels from getting scummy or worse, I'm
thinking of adding bleach -- not enough to render the water dangerous
to plants, but enough to keep it safe.

How much per 32 gal. trash can would fill that bill?

1 ts per 5 gallons.

Chlorine bleach evaporates quickly... "1 ts" won't do a whit and
within a couple hours it'll be like it was never there at all.

1 TS per 5 gallons is the USDA recommended amount to render clear water
safe for drinking.

According to a couple of sites I looked at, it's a half a teaspoon per 5
gallons. But I doubt whether doubling the dose would be a problem and I
wouldn't even bother to add any for such a small amount of water. I'd worry
more about mosquitos breeding in it so would use it quick sticks.
