filter cycling

[Harriet]

i have three tanks and one of them had a cycle crash due to medication which was no problem as i was moving the fish to a bigger tank and had a spare tank anyway now i’m trying to recycle the tank and have put the filter in an already cycled tank and i’m wondering how long it will take for the filter to build up enough BB so it can go back in the other tank again with some fish sorry if this is confusing i didn’t really know how to word it

If you just squeeze out the media from the cycled filter into the new tank, that filter should be seeded and ready in 4-12 days, depending how much you squeezed out.

What kind of a filter are you running?

I always just move some of my established filter media into the uncycled filter and am cycled almost instantly.
