No it isn't too soon - to unhook the pump, filter, etc and to stop feeding
the koi.
Be sure you have a bubbler hooked up for keeping a hole in the ice ...
Water temps of 55 degrees F. are usually the cut off point for feeding the
fish.
If you don't have a water thermometer ... please buy one. You'll need it
for
spring start up.

Greetings all,
i have a 2500 gallon backyard pond here on Long Island, New york. It
is starting to get around freezing here now. When should i disconnect
my submersible pump and dump out the biofilter, etc...? Is it too soon?
Have a Laguna WG 10,000 pump and a Laguna 4500 pond filter. Also should
i stop feeding now. Have about twelve 9 inch koi.

Thanks,
Tony
