Years of Grass Carp & Tilapia have lelft the pond almost weed free for 20+ years. This has done a number on the fish balance in the pond. I now understand that having a 20% weed cover would be a good thing.
A 3 acre pond in North Florida with only one Grass Carp surviving. To the best of my knowledge the Tilapia are few & far between. Only about a dozen very mature tilapia seen in the fall. Never seen anything less than 13". Pond has been LMB over populated for some time. Visibility 2'. Ph near 7. Herons, geese, anhinga, shore birds are regular visitors.
Letting Mother Nature take its course how many years might it take for weeds to return?
Any ideas to speed the process up without investing big bucks?
