How long does it take for ammonia to be broken down to nitrite/nitrate in
a
new filter? I have had my new drip filter going for approximately 4 weeks
and so far my tests only read ammonia. Isin't it about time that the
tests
show some nitrite buil-up?

=========================
Your pond is very overcrowded. Koi, like goldfish produce a lot of waste.
You will need to build a much bigger pond and very soon if you want to keep
koi. You are doing massive daily water changes aren't you? If not the
ammonia will eventually kill all your fish.
