Hi all. I am looking to get my 40b going again and my wife really wants sw. I did it before but very half arsed. I would like to do an overflow with a sump this time. I was going to go with a mp10 for in tank flow along with the return. Last time I had a hob skimmer......how do I size a overflow and return pump for this? I was going to do a reef but basic corals. Any suggestions on equipment is welcome. I was going to make a purchase on stuff today from BRS for the big black Friday deals ?
