Hye BTB, are you planning on using a UV filter in the near future? If so think about this, you have way to much flow to utilize a UV. You could cut in a Y fitting above the sump, install a ball valve,install your hose and up to your other return. This way if you do end up adding one down the road just stop the water cut in your UV. Plus w/ the ball valve you can control how much water flows through it. So what I might suggest is think about this before you start cycling and adding fish.
Just trying to help
