Pond Boss Forums MANAGING AN EXISTING POND Evaluating and adjusting fish populations YP, SMB and... goldfish???

Lower your water level as much as possible and add 250-400 pounds of HYDRATED lime per surface acre and it will kill those buggers for ya! Spread it on all wet areas also to kill of any unknow species that may be in the pond/mud.

Let the pond refill and all will be great for a spring stocking.
