I think everybodys got it right you're just seeing it from a few different angles. Moving the filter or washing it out into the new tank works wonders and you usually won't see an NO2 spike or ammonia. You should still monitor for these especially if you've decided to use an antibiotic, which can mess up <any> bacterial colony and cause NO2 spikes. Most of the times it's a parasite anyway so you should probably think about treating for that first. If you are doing treatments on the tank it's also a good idea to change 50% or more of the water, at least every other day. That doesn't have to be tap water but can come from one of your healthy other tanks. Feed lightly and if possible feed quality frozen foods or live foods to ensure that everything is eaten to avoid adding extra ammonia to the system. Just keep checking to make sure you don't get an ammonia spike.

Well, my experience is that if you don't wait a bit, and just add a
bunch of fish to a completely new tank, you'll get a NO2 spike which
can be deadly to the fish, especially if they're already sick. Of
course, adding existing filter media solves that problem since that
introduces enough bacteria to get started. Using water from a running
tank also does that, but there aren't a lot of nitrifying bacteria in
the water, more in the filter and the ground substrate.

On the other hand, I believe you do weekly water changes? That of
course also helps in avoiding the NO2 spike. But I've read a lot of
stories of people (on dutch forums) that buy a tank, fill it with
water and put a dozen fish in it (all on the same day) and think that
everything will run smoothly for a month or so before they have to do
anything else. Well, it won't...
