Split drain or split return?
I'm just about to start plumbing my 90 gallon over a 75 gallon sump.
My 90 has a 600 GPH drain and I'll be running a MAG 12.
I'm planning on splitting my returns and I calculated that I should be running about 500 GPH up to the tank.
Now my question.
Split drain (1 - Refugium / 2 - Skimmer Section)
Split return (1 - Refugium / 2 - return to tank)
Both will have valves to control the amount of flow.
Any drawbacks or benefits of each?
Thanks
-Jeff
