Need help with tank plumbing (first time)

[baker_jeff]

Alright folks. My stand is finally ready, so I am starting to work on the plubing. It is a 30 gallon display, with a 20 gallon sump.

I have a MaxiJet 1200 as a return pump. The sump is about 20-25 inches below the display. Will this be powerful enough to pump water back up? Should the powerhead be below in the sump or up high near the display?

For my return line and drains, is 1/2" PVC pipe large enough? I have it on hand so it would be more convinient.

I will post more questions as they come along.

Thank you for your input!

Jeff
