So my pond isn't clear but its gray. I had an algae bloom so I sprayed algaecide to get rid of it. The algae died and the pond went from pea soup green to a dull gray color. So I've spread about 150 pounds of alum in the pond at 50 pound increments every week. the pond isn't solid gray but it still has a clear gray color to it. I started out this year with a perfectly clear pond and I would like to get back there. Any advice?
