Herb vs bean
I asked the same question when i was building my 1st reef tank. You can be successful with either method but 1 may fit your build better.
What are you starting with tank/sump drilled or not?
Do you want corner overflow or box inside/ghost?
My first build i used a 714gph pump on a 30g display/15g sump. This worked but was way too much flow.
2nd build is 90g display with 30g sump, i am using the same 714 pump and it seems like the right amount of flow.
5x water volume is what i like. Some say 10x but i think it just sweeps all the pods right out and into the display.
Dont oversize your plumbing too much, using the smallest size at full siphon restricted with a value just a touch will stay clean alot better than a 1 1/2" drain choked way back.
