once the aquarium is cycled then check the nitrates. if the temps inside is
significantly cooler (basement) dont feed them that often. high quality food has
less waste. 4-5 flakes of food twice a day is normal feeding of 5-7 inchers. if
you only want to change water once a week, then adjust feeding so nitrate levels only
reach 20 ppm per week.
be sure to keep top covered, that koi will jump.
it is possible to keep your fish outside in winter. I do with a heater, a bucket
filter and plastic cover on my pond. altho we only get -20oF here.

Hello. I just had my first pond this summer and things went fairly well. I
have 1 koi and 3 goldfish and I live in Canada where they would not survive
the -40 weather in January so I brought them in the other day. My question
is now what, how much, and often to feed the 4 of them. The koi is about 7
inches, the others are about 5. They are now all in a 70 gallon aquarium.
I have been giving them pellet food in the pond on occasion and they really
have been fattened up on all the crickets we had the last month that
committed suicide in the pond. Do I continue with the pellet food in the
house and feed them every other day, or what is the guidelines here? I
don't want to overfeed them and deal with all the poop they will be putting
out. By the way, I have a fluval 304 filter hooked up to the tank.

Thanks.
