Pond Boss Forums AQUATIC VEGETATION Controlling unwanted plants eat fish from copper treated pond?

Tilapia are illegal in Illinois cause apparently they wear little snow suits and live thru the winter here.

I want to add crawfish but I am light on predators in the pond so I want them focusing on BG spawn, not crawfish. Hope to have them once I get things balanced a little better. Also want to get the vegetation established before bringing in those two clawed lawn mowers!
