Hi, newbie here although I have had my pond for 20yr and it is about 40 yr old.
My new neighbors have a horse farm and I get runoff so the nutrient balance is changing.
I also have some trees down in the pond and that helps add crud to it.
Now about 4 yrs ago, I had a major duckweed infestation and it was easily fixed with fluridone. I have had some duckweek in the pond ever since but it has not become invasive.
Now to this year. Duckweed is back but not covering the pond. I have fluridone on the way and probably <a quart will help this.
The biggest problem is a brown algae bloom that seemed to appear almost overnight and covers the pond. It seems to be a very fine algae and appears to have some filaments coming from parts of it. In the morning, it seems to be bubbling so I assume it may be putting out some oxygen. I sprayed some of it yesterday with cutrine and some captan. Does anyone know what kind of algae this is and the best way to control it?
I am also looking at aeration systems. What do you folks think about the Thomas systems that are sold on ebay?
The pond appears to be a muck bottom from what I read. (odoriferous black mud.
This pond has always dropped a lot in the summer but last year's drought got it lower than I have ever seen it.
Any input and/or suggestions?
I appreciate you guys reading this.
Thanks
Bob
oh, the pond is about 1 acre and about 9 feet at it's deepest.
