We have found this skimmer to be very good for Koi ponds for several reasons.
It is not a "Koi Killer". It skims a "knife edge" of water, which prevents Koi from getting swept in. Standard skimmers have Weir doors that allow Koi to swim or get sucked in, but prevent them from getting back out. Finally the Koi get exhausted and die.
It has an adapter for connecting a vacuum hose directly to it so you can vacuum the bottom of your pond.
