Thank you very much for the info. I will start to research Tannin treatment. I know carbon is used to clear it, but our pond is too big for that. Will the water ever naturally clear? Right now it looks like a tea/coffee color. Is it a waste of money to even put dye in? We were at a pond seminar and the speaker told us if we put the dye in it would just mix and make an odd color then eventually go to the bottom quicker.
