What size pump?

[cam78]

I am currently in the process of making a 10 gallon refugium tank for my 46 bow. I need to know what kind of pump I will need to pump back into my DT. If someone can give me a good name brand and size it will help me put my last baffle in place. I don't know how close to put the last baffle towards the end of the tank. Can someone help me out or just give me a measurement on how far to place this baffle? I am limited in space due to the 10 gallon so I would like to place it as close as possible to the edge. Thank you!

what rating over flow do u have?

I am either getting a CPR CS 50 or CS 90 whatever someone thinks I'll need or I'll be getting the Lifereef. I think the Lifereef is to big for my tank though. Any recommendations? I'll be getting the overflows because my tank is not drilled.

Would a CS 90 overflow (600 GPH) and a Mag Drive pump (500 GPH) work well together for my 46 gallon Dt and a 10 gallon Sump? Also can I not submerge the pump and just use clear lines so this way I don't need so much room inside the 10 gallon to submerge a pump that is 5" X 5"? Please answer, thank you.

Besides the overflow rating Peckhead mentioned, you'll also need to know your "head", which is how far up the pump has to push the water to the point that it returns back into your tank. This will have an impact on pump selection as it can cut the GPH re-entering the tank significantly.
Just pulling numbers out of the air as an example, say your pump is on the bottom of your 2-foot tall stand, and the return puts the water back in your 2-foot tall tank at the top, then you have a 4-foot head (2-feet for the stand + 2-feet for the tank), AKA "headloss". Any angles and bends in the return plumbing can also increase the headloss since your pump will have more flow restrictions to deal with.
Some sites that sell pumps, as well as the pump manufacturer's sites have flow-charts that give the respective GPH at various heads for the pumps they offer. They should also have the physical dimensions as well.
I don't think a 500GPH pump will do the trick for you . . . my 700GPH Mag7 only puts about 480GPH back into the tank with a 4-foot head.

I just ordered a Lifereef overflow and he suggested a Henri PS7 pump which puts out 500 gph at 4 ft. which is how high my floor to top of tank is. We will see.
