Plumbing questions

Using larger diameter pipe and using as little pipe length as possible will help increase flow. However the biggest limitations are the 1" intake and the two SCWDs so it's hard to say if you can greatly increase the flow without removing those limitations.

I can drill the intake larger but the pump only has a 3/4" intake anyways. I could remove the SCWDs and just feed to 2 of the 3/4" outlets. That would simplify the plumbing

Pumps usually have smaller inputs and outputs but the piping should be larger. If you can run 1.5" pump straight from a 1.5" bulkhead to the pump and then larger pipe again for the outputs it will help. 4 3/4" bulkheads for output will actually match up nicely to a single 1.5" input.

Thanks for the info.
I was figuring oversizing by .25 was plenty
I will see if I can fit larger piping coming down from the tank. I do have a spare 1.5" bulkhead around here somewhere.

The 90 degree bend into the SCWD is robbing you of flow, maybe as much as 30%, the SCWD accounts for 20%

You should consider putting in a nice OceanMotion 4way instead of the SQWDs. I've run both and the OM4way is the way to go!

The OM4way is the way I wanted to go but the price tag kept me back. Im going to try a few piping changes and see if the flow improves.
My need to get this tank in service has greatly increased do to the flood downstairs. I hate having to put rubber boots on to feed my fish.
