Was wondering if there is anyway to get rid of duckweek, massive amounts in a natural pond, they remove it as best they can and within 2 days it is completey covered. I suggested grass carp, is there any other suggestions? Presently they have bass in the pond.
Copper will remove the duckweed (and probably kill the fish too.)
Ranchu goldfish will eat prodigious amounts of Duckweed as long as they are sizeable, say 4-6 inches in length. Grass carp are affordable solutions but they will root up the Bass beds in a natural pond, and stop the sport fish reproduction, do they care?
Koi will also eat duck weed with zeal if they aren't fed anything else.

A plain old skimmer could pull the duckweed out, the large Oase pumps can handle solids of this kind up to 5/16th of an inch and could simply chuck the duck weed into the garden. Do you have a reasonable source for replacement water or should the Oase shoot the water through a window screen on a frame?
