Killing Algae in Backyard Fishpond

I use a product called AlgaeFix. It is safe for fish & plants, I have aprroximately 25 fish in my pond & lots of plants & have never had an issues. It works very well.

BTW, vinegar will change the pH of the water and could easily kill your fish.

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.

Good luck!

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.

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.
