It is irrelevant if you have a big filter - it is a biofilter, and biofilters take time to get established. It won't necessarily establish faster because it is bigger.
The only real hope is a lot of established live rock.
Even then, it is not likely you will have several large fish if that is your goal. Of course if it is all for show...and I've seen that
...then you will be able to probably keep them alive for a few days.
Otherwise, it is a hobby based on patience. While you could get some fish in there, IMO, if you buy established live rock from someone's tank...getting a lot of fish, or large fish, is an issue.
If you have bought real dead coral, and have a lot invested, I would not use it in a tank. If it is dyed or bleached that could be a possible issue...and it will be covered in algae. Often times the real coral skeletons become weak and break. So if you value those dead corals, I would not use them in a tank
