Lap's 90 Gal Reef - Need flow help

[Ryan_Lap]

I need some opinions on how much flow I should have. The thing that Im confused about is Im running a nano wavebox, so I dont know where the gph factor in for it.

Currently running a:

Nano Wavebox (??)
Koralia 4 (approx 1200 gph)
Single Return (approx 1017gph) probably lower

Not sure what my flow in gph should be so any help appreciated.

As for corals I plan on keeping a few acros, some monti digis, zoas, and lps on the sand or lower

Would a single koralia 4 be enough to add?

Thanks
