I put in two grass carp back in January. I only put in two because at the time I did not have any kind of vegetation problem. I added 5 lbs of tilapia at the end of April, but I don't know if they will help out with the naiad.

Weedplex Pro...I was concerned about how to apply it as you can see from my first post in this thread. The label only tells you that the container 'Makes 100 gallons'. There are no directions on how to apply it!?

Do you think more tilapia would maybe help? I have a minnow pond that I put a few tilapia in and they have raised twice already. I would estimate that I have a ton of tilapia that are just over 2" and the second hatch are around 1". I plan to move them to my big pond within the next week.

Thanks for the help.
