Hi - I will be setting up a 29 gal
tank with a 10 gal
as a sump. I purchased a Mag 7 pump a a real good price and realize that it may be a bit of overkill for a 29 gal
tank. As you can see from the drawing (a paint quickie) I have a return line going back to the sump, I thought that would keep from restricting the pump too much. I was thinking of adding a UV
unit to the return line, is it worth it? Oh, the overflow is a U tube type rated at about 500 gph
, I figure that with a 3' head the Mag 7 would be about 500 gph
. The drain line will be 1" what should the return be 1/2" or 3/4"?
