Sump recommendation

[snowcap]

I am building a 120 sps tank and am wondering if a 40 gallon sump is good enough due to space limitation. I would have a compartment for an in sump skimmer and a section for a refugium
Would appreciate your thoughts

u can fit much bigger sump under a 120

The 40 gallon would work just fine.
