yeap they use a blueline pump also, not sure of the model. Due to its offset return you cant get a line up of the plumbing like you can with a maxijet and have to drill the holes on the tube on different axis...
did some more work on it today.. routed out the base. I made the base square for more stability due to the reactors size and large pump hanging off it side

And the moment of truth, the water test..... i added a small pipe so you can see the water flow (air bubbles)
