Suggestions please for a new filtration system in a 210

[Fishy8575]

Hello
I am new to this board! We have a 210 gallon saltwater tank with fish and corals. Currently we have 2 tide pools. We want to upgrade to a new system - with one big enough for the tank. We are not sure what we want but need some thoughts from you all. We also want to run an external pump. Any suggestions for that? We have a good skimmer now so we may not need a set up with one. Thanks in advance.
