Have the same rust colored water in my 2 acre pond in East Tx. The pond and surronding 25 acre's are thick with Oak & Sweet Gum trees , what a mess in the fall . when the feeder go's off i can't hardly see the brim & c-cat take the feed. could this cause any fish problems. I don't aireate, & the deepest part is 8' but most of the pond is shallower. also have grass carp & black bass. plan to wait and see if it clears after the leaves decompose before thinking about aluminum sulfate. Any suggestions or comments. Harvey
