Help cycle a new tank with existing media

My 10G started to leak so I got myself a new one. I'm thinking to put new substrate in the new tank, add my plants and my fish and add water. Some people say to get a new filter for the new tank and use some media from my old tank. Why not just use the old filter on the new tank?

If you are using new substrate, all the more reason to use the old filter/filter media. Simpler to use the entire old filter rather than just the media. Unless it is broken of course.

Keep in mind that there are lots of people wo will tell you lots of things that you should really ignore?
Keeping the old filter and media is the best way to go any time you have the choice. Bacteria will be on everything in an older well established tank. That means the tank, the substrate, the filter media as well as the filter itself. So changing out to a new tank, you are losing some bacteria so it is not good to ditch any more by changing filters.

Stable is good! Small rocking of the boat is better than large rocking the boat. Just watch for any spikes that might come round and it will be fine to keep the old filter.

Hello niz...

If the old tank was established, then take everything from that tank and transfer it to the new one. In a cycled tank, everything with a surface will have good bacteria living on it.

If the filter is too old, you might wanna change the impeller and the motor but rest of it should be better than any new filter for the tank.
