Looks like we should have warm water temps for at least a few weeks yet so I've got some FHM coming. Will be neat to see something swimming around in there in any case. Was thinking of adding a few hundred BG, PS and GS in the Spring, do you think there's any danger of them taking over in a pond that's goal is to catch predominately Yellow Perch and various trout in the end? I would tend to think the trout will control them to a degree?
