Pond Boss Forums STOCKING A NEW POND Creating the food chain First attempt at pond management: LMB vs SMB

Duckweed in a newly built pond? That is rare since duckweed is characteristic of older, organic laden, eutrophic ponds. If the pond is new DWeed may not return after the pond has stabilized next year. Annual duck weed problems indicate poor and risky water quality for raising SMB who prefer higher DO concentrations. Expect frequent DO sags in ponds infested with DW.
