HOB filter for saltwater 30g?

[Ice Man]

Can I use HOB filter for saltwater tank? Maybe canister filter?
Or is sump my only option?

For now it's only gonna be FOWLR. I'm planning on getting at least 30lb of live rock and around 30lb of live sand. Already have a HOB protein skimmer.

A HOB filter is just fine it is really only for mechanical filtration your LR will handle the Bioload

Thanks. I figure if I get filter rated for at least 60-70 gallons then it should be ok.
