Thanks every one, since the neck is 6"OD, I want a pump that pulls at least 2000 lph start with and then I can tweak it up to 3000 or more to accomodate the neck size...thinking about Bubble blaster or Laguna pump.

I really like the DC skimmer pumps.
how much is the acrylic costing you and where did u find the cylinders
Pro status!
