Is there a recipe for vinegar to use in backyard ponds with fish? The pond has algae on top. I want to kill the algae without killing fish. The algae is taking the oxygen away from the fish. Please help.

Clean as much out as you can and then take an onion bag and fill it with straw.This should keep the algae away. I don't know about the vinegar it might kill the fish.
I wouldn't use vinegar without checking with a reliable source. I had a fish pond for years with no problem. Do you have any plants in the pond? Water hyacinths are supposed to help. In the house, I have algae eaters in the aquarium.
I've seen products for sale called barley straw balls, which is supposed to deter the formation of the algae, so I would think you could try wheat or oat straw, if that's more readily available to you, but you should try to give it some sort of floating assistance, like tie on a sealed empty plastic bottle.
BTW, vinegar will change the pH of the water and could easily kill your fish.
