being new to the pond world I am looking for help in clearing the water in
the pond at my new house. filters are running, bubbler is working, but pond
is green and murky. I am assuming it is an algae problem as the rocks in
the waterfall are covered with a green slime. There are largish koi in
there that I see occasionally (when I feed them mainly). Please tell me
what I can do that is not chemically based. If all you say is it's in the
archives please tell me how to get there too as I tried once and never did
find them.
