It would be very interesting to hear an update from "airborne3118". GSF can be effectively controlled by LMB and CC if predators are allowed to become dominant /abundant. The addition of BG will also help compete against and out populate the GSF. Numerous pondowners have proven that GSF can be effectively and successfully managed without renovating the pond.
