Mulm/debris from other filters..can i add it to my new-ish tank?

So, yesterday i did a bit of rinsing/cleaning of some of my other tanks filters, and go a whole bunch of mulm/debris, which im assuming is rish in healthy bacteria!
One of my tanks, a newer one, is struggling with ammonia/ammonium.
Would i be able to add this mulm/bacteria to the tank to help with its bacteria colony?
How much should i add? To the filter, or the tank itself? It does have new substrate only a few weeks old, but not new filter media, that had been set up for a while now.
There are fish in the tank, will adding this stuff be bad for them?

Its in a bucket with an airstone, so the bacteria is still alive..waiting on you guys to tel;l me what i should do!

50g, 45g, 15g, 10g, 2x2.5g, 2g bowl

Personally I wouldn't just throw it in the tank. I would try to get some media from the struggling tank and put it into the bucket with the mulm and debris, and use it to seed materials heading back into the tank that is struggling. Just my .02$

29g Tetra Tank
100g Planted Angel/Clown Loach

That's how I cycle new tanks - Just add lots of mulm and it cycles in days. I usually just dump a container full of mulm right into the tank. I do it before adding fish, but I don't think it would bother them if you just dumped it in. But you could just try adding some to your filter, to see if it all gets trapped by the filter. If it does, then just add as much as you like. Otherwise, you may want to take it slow and add a little at a time.

Life isn't stone, it's water.

PSA: When talking about baby fish, "fry" is plural.
I have a fry. I have some fry.

Old sponge or filth from the sediment, deep vacuuming etc.
Plant roots from a well established tank etc and of course, plants themselves make the cycle silent, since they use NH4 directly, I've never had a cycle really for decades.

Anyway, you should be doing frequent large water changes for the 1st month or two anyway, so nothing will build up anyhow. Cycling really has no place I can rationalize in the planted tank hobby.
