Ok, I have a 190 gallon aquarium( in wall) that I am setting up, it has overflow box with 3 holes drilled, 2 holes with 1-1/2" bulkheads and 1 hole with 1" bulkhead. I also have 4 holes drilled in the back with 1" bulkheads.
My return pump is a Sequence Marlin (2050 GPH), it will also be teed at some point to run skimmer, but not at first.

Not sure what the closed loop pump will be, I have an Iwaki 40RXLT that I was going to use but it is not running correctly, I assume the brushes are out on it? It will run if you get it started by spinning it by hand, but it want start turning on its own.

My questions are what bulkhead holes should I use for return and what should I use for intake on close loop?

Any thoughts and help appreciated.
