Even thinking about turning my 46gal bow front to a fowlr. Never done saltwater before. Looking at the koralina power heads. I was told I need one on each end. My question is what ones would I need? How many gph for each one.
For me it is just trial and error. I have 2 550's in my 29, and a 1050 and a 750 in my 75 along with the returns from the sump. So, I think the 750 would work well for your tank.
