Pond Frog & CJBS2000:
Thanks for the input . My main concern was if the plants were being eaten by the fish; water quality issue; or lack of planting properly. I tried coontail last year, and eelgrass(Vallisneria)two years ago. I just threw them in the pond. I don't believe they survived longer than 1 month.
I won't add any non-native plants, and want to pick a type that triploid grass carp will eat if the plants start to get out of control.
Any other input on this?
