Return Piping In the Tank

[magyk]

Running 1/2" vinyl tubing for the return from the sump into the tank now how long should the spray bar be (this will be made out of PVC)
I'm using a Mag 5
and should I use schedule 40 or 80

use sched 40...with a mag 5 a spray bar of about 10-12 inches with 3/16th holes spaced about 1 inch a part should be ok.
