Pond Boss Forums AQUATIC VEGETATION Controlling unwanted plants Can Tilapia do harm?

Natures clean up crew (raccoons, opossums, turkey vultures, etc) will also remove Tilapia from the pond. Yes, the excess nutrients most likely came from the decaying vegetation. There only two other ways to fight the algae problem.

Stocking Tilapia. They eat the FA, and are removed from the pond in the fall, either by you or by nature.

Put aluminum sulfate in the pond to bind up the P.

My vote goes to the Tilapia.

The horsetail is there because of the varying water levels. If you can keep the water at the same level, the horsetail will be out competed by other plants.
