Was the waterfall part of the filter? That should never be turned off. Red veins can be caused by a bacterial infection, a parasite infection or ammonia or nitrite poisoning. Not keeping the filter on could of caused those things. When you added new water did you dechlorinate it?
Koi need 250 each and shouldn't be in a pond less then 1000 gallons.

it sounds like your water quality got really bad (cloudy) which caused a bacterial infection, then when you changed the water
you put further stress on your fish and they died
take better care of the water, do regular water changes and be sure to dechlorinate each time, also add aquarium salt as a good
healing and reventative treatment
get a good book about koi and ponds for information
