I don't see how kch, since goldfish really are nasty, dirty fish. I've heard of them being used to control mosquito larvae in stock tanks, but not algae.
When they're in an aquarium either snails or algae eater fish have to be put in with them, because their tank will get disgusting and algae covered otherwise.
But hey, if you say it works for you and you're happy with 'em, then who am I to say otherwise?
My water tanks are only 70 gallons and they get dumped and scrubbed every other week anyway, so fish aren't necessary. Besides, my barn cats would see them as fast food, and make quick work of them!
