We have a 1350 gallon pond in our courtyard. It sits in the sun for most of the day. After reading various posts here, in regard to clearing up algae, we have installed what resembles a sail high over the pond in order to provide shade. I hope to be able to remove this after we have added more plants to the surface of the pond. We are using a pump that is sufficient for the size of our pond. We have installed the pump into a milk crate that’s been covered with quilt batting which acts as a big filtration system. After the water goes thru the pump, it goes thru a uv light. I am including a “before” photo with this post. I hope I can follow up this post with an improved “after” photo. If all of these measures don’t work out, I give up!
