Ro regal 300int on 220g

[Rawsreef]

I found a good deal on a regal 300 int

Is it worth buying this to run on my 220g?

Heavily stocked tank, feed heavy also.

Currently running an undersized 150s. Is it better to be grossly undersized? Or grossly oversized? Lol

I always thought to get the biggest skimmer possible, however from my research it appears that under sizing is a far better choice. An even better choice would be to run two smaller skimmers vs 1 large.
