What Size Do You Like for Reef Sump in 4x2x2 tank Stand?

heres another pointer setup the feed hose for your skimmer run it into a five gallon bucket and time how long it takes to fill,from that you can calculate your pump size. A little underpowered is good,it lets you adjust flow from the skimmer side because if you turn the valve on the pump side down you'll put strain on the pump due to backpressure and prematurelly burn out your pump
