New filter in tank

[fishkeeper01]

Is it ok to put a brand new filter on an existing tank?

If an already cycled filter is also left on the tank, that is fine. the new one will become seeded.
Alternately, if you put a bunch of bio-media from a cycled tank inside the new one then it's good to go. You just need adequate amount of established media for the tank's population/bioload.

How long till the new one can run on its own? Also putting the new filter on an already established tank still requires the old one?

How long till the new one can run on its own? If you don't put any media from a working filter inside it, I am not sure. probably into several weeks.
Also putting the new filter on an already established tank still requires the old one? Tanks are mostly "established" by the filtration system which does the waste conversion work. There is some beneficial bacteria on other surfaces, but you need a sufficient beneficial bacteria-to waste-ratio in order to prevent toxic levels of ammonia & nitrite.

Read the sticky primer about "Cycling tanks" at top of this section of forum.

Lots more info is needed, but as above said you can easily find the info.

This is a tank that already has fish and I was just simply changing to a different filter since the current one broke.
