A few of these; a few solar panels to run them....
Even running aerators might not help without solving the nutrient problem.
But it makes me think of some things I learned when trying to figure out what to do with the large quantities of tiny Azolla Fern that grow on top of my pond at times. The fern’s root is like one thread that hangs down, and the algae tend to accumulate there. The algae and the fern trap nitrogen, so in turn the fern/algae makes a good mix for compost/mulch.
Which begs the question- if we’ve basically created an algae farm, then why not use the algae for something instead of letting it die and cause bigger problems? Something else I noticed about algae, when it’s dry it’s kind-of cottony. I wonder if the dried algae could be made into something? I can tell you than if you leave a clump of the algae/fern mix to dry in a lump it becomes almost indestructible.
oh well probably a bunch of silly musings on my part.
