I too thought maybe I should get a Barracuda for the return. I was told that the 1" bulkheads that I have could not handle it. My reeflo Dart was cranked down about 1/3 for the first 3 weeks and is now cranked down to 1/4. I think a Dart would be as big as I would go with 1" bulkheads. That should be a lot of flow for a 4ft tank. If I did not have filter socks on my drains I would have serious microbubbles with almost 2000gph going through this
sump. The sound a Barracuda would make would sound like a geyser in my opinion because the drains woudl not be able to keep up with the flow. You still may need an additional pump or two with the Dart but will have some serious flow if you do. I hate to see you buy and plumb the Cuda and then ask yourself why you did not go with something with less head pressure. How many feet will the Barracuda have to push the water?
