Why in My Pond? (Duckweed) - 08/11/03 02:52 PM
Boy am I glad to find this site! Seems like all the others that I could find only pertained to 100 gal. garden ponds.
My 3/4 acre pond is almost 5 years old now and for the last 3 1/2 years I've had a duckweed problem. Normaly, I'll skim the surface once a week (all summer)and scoop out probably 80% of the weed and a week later the pond is completely covered again. I'm hesitant to use any chemicals for fear of harming my fish (catfish, crappies, perch, hybrid sunfish) or my snails, clams, crayfish, etc.
Nobody else in the area seems to have this problem. What is it that makes my pond such great duckweed habitat and is there anything I can do to eliminate it and not harm my fish? I'm at wits end and about ready to drain the pond and start over. Help!
