Also had another idea. Since i'm in the middle of digging my pond out I was thinking. Would it be helping to spread alum out along the bottom before the water fills it up or would that be a waste? Is there anything you can do before the water comes to help with the clarity. Would spreading the ag lime over the clay layer help or just a waste of money? I know I ramble lot my wife tells me all the time. I say I'm a thinker and a doer lol (more thinking than doing). Right now as the water runs over the topsoil its clear and as soon as it hits the clay its murky. Just seems like maybe theres a way to avoid the murkiness before it happen. Is it a good idea to put topsoil on top of the clay layer when done digging?
