Is this Protein skimmer enough?

[Jaybeastin]

I have a brand new Reef Octopus Classic 110int Protein Skimmer for a Red Sea 350 total 91g volume. I’m wondering if it’s enough for 6-8 fish, but with 2 TANGS. I do 20% water changes biweekly and occasionally 3 weeks. Returning is a pain in the butt but should I upgrade for future benefits?

Most likely.
