whats a good pump?

[hockey nut]

Hi all, I have just purchased a 120gal with dual overflows. Any recomondations on size and type of pump. I can't remember off hand how many gallons the oveflows move per hour. Any help would be great. I am allready curing some new lv rock as well as sand to add with what I have from my 70gal. I have yet to build the stand but should have that done soon. Lots to do yet, but hopfully should have her up and running buy the middle of September. Any ideas on the pump would be appreciated. cheers
