I wasn't sure where to put this but I'm sure someone will let me know if it's in the wrong place. We have a major problem with blanket algae. We have no fish or plants in the pond yet and the pond is fed by water coming down the valley when it rains, across fields that are fertilized by muck spreading and even then not many of them. Any idea on how to get rid? Please don't suggest barley straw as we can't  get hold of any. My main concern is that it will deoxygenate the water just as we want to strt introducing edible water plants.

No experience, but these are the best looking links I have found so far(many were about small tanks and/or had bad advice):

https://blog.pondking.com/algae-eating-fish-for-ponds

https://pondinformer.com/pond-fish-that-eat-algae-guide/


Please don't stock invasive/tropical fish if they can escape out of your pond(either upstream or downstream); you don't want to be responsible for starting an ecological disaster in your own backyard.

Thank you Dustin! We weren't  thinking of any fish other than gold fish just to eat mosquito larvae but we could look at these.

I don't know if this helps you, but one of our mini-ponds, which gets runoff from the neighbour's horse paddock, grew a lot of algae mats over the summer. Last week I noticed a "wild" duck hanging out on it. By about the third day after she appeared, all the mats were gone. I can only surmise that she ate it.

The other small pond is not growing much algae. It's covered in azolla, though. I don't know if there's a correlation here.
