Okay, first the snapping turtle, now the algae. I recently had what I thought was my first algae bloom for this year. A scummy looking substance that over the course of a few days took over the whole surface of my pond turning more green every day. I treated the surface of the pond with copper sulfate. By the next day the pond was free of the scum and clear again. That was last week, starting a couple days ago I noticed a subsurface green band running through the pond, yesterday the whole pond had almost taken on the color, and now today the pond water is green. Not really any floating green scum, just green water, you can still see down into the water about a foot. What's going on? Do I treat again with Copper sulfate, or do I let this go? The first bloom I let go for a little over a week before treating it, I thought you did this so the microscopic food could multiply and jumpstart the food chain. Any help will be appreciated, the pond is between a 1/4 and 1/2 acre and 12 feet deep to 6 feet in shallow end. And yes, there are fish ini it.
