Fish Ded, Cycle Pond?

[clemsonguy1125]

I just moved in my pond to my garage. I filled half, waited a day and filled the rest. I added a trio of "feeder fish" aka comet goldfish. None of them made it through the night. When I had the pond outside I filled it, waited a couple days and add several fish. It was fine for a couple weeks then so much clay fell in the pond I had to clean it. When I added the fish back, they all dies. From what I read, this could be caused by not cycling the tank but the weird thing is that the traditional way of cycling is by adding these fish. They were small at about 1-2 inches. I dont have to pump in because it winter. I have it in a small plastic fish tank next to the pond. Im working on a cascade filter. I think ill set it up to get some aeration. Anything elso I can do to help with the cycling issue?
Thanks

Any info on pond size, age of pond?

You say you don't have a pump but you do have a filter? confused about that for a cascade type filter (or any for that matter) some sort of pump/powerhead is needed?

Did you treat the water(prime)?

How cold is it?

If you just drop them into the water in the winter, most likely it would be shock that kiled them, aclimate your fish, use Prime, filter your water for at least a week or 2 without fish in it at first with just the Prime, add the feeders, and it'll cycle in about a month to a month and a half.
