Believe me, it took awhile to figure it out. LOL.
I will get the two jars and water samples. Is the Alum the same alum that you can get at the grocery store?
Our pond has water lilies and some pond grasses by the "dam". Normally it has a lot of vegetation in the middle by now, but there is none. Last year I pulled a lot of it out. filled a small boat 3 times. I'm thinking I have really messed things up here. Is there a way to get rid of the bluegill? They are way too prolific! When the horses are out, they do get in the pond and splash around. Of course that leaves it murky, but it has always cleared up by the next day. Last year we did have the green algae "bloom" I think they call it. We don't lose fish and everything in the pond appears OK.
