Ok, my new tank should be here on Friday! I have been ordering and collecting my equipment for a little while now. I am going to follow the BRS/WWC Hybrid method for the most part. One of my first questions is about my return pump hard plumbing. I am going to do a manifold. I ordered the Abyzz A200 DC Controllable Pump (4,400 GPH) as my return pump. The inlet of the pump is 2 inches and the outlet is 1.5 inches. I don't know exactly what the dimension of the pipes on the red sea will be but I believe they are around 3/4 inch. My question is should I restrict the outlet of the pump to closely match the pipes of the Red Sea return or should I plumb everything at 1.5 inches and restrict the return to the tank? Thank you for the help!
