Larry - No problems with the eelgrass at least for the first 4-8 years depending on the bottom composition. Keep an eye on the depth distribution. Once it gets too thick(?) start with only a few amurs; you can always add extra as needed. Allow them in the pond for at least 2 yrs before adding more. They need to get some size (20-28") before really doing a good job mowing eelgrass. IMPORTANT: don't get too many amur in the pond they CAN EASILY eliminate the eelgrass. You are better off getting a Y shaped lake-weed cutter and thinning the eelgrass yourself to help the amur keep it under control.
