Help: How to split line coming down from DT?

About to order my plumbing for the plumbing for my tank (90 gal with 20 gal sump, skimmer/return/fugue) Sump located in stand. My question is how do i split the line so the skimmer and fuge get flow. I know i have read you run a horizontal line across the sump and make a t at the bottom of the line with ball valve. But that would require an extra 2 to 3 feet of extra flex tubing and seems very inefficient. Can someone please give me some input on how i Will accomplish this with flex tubing?

Thank you!

 

For my drain I used PVC pie and not the flex tubing. Basically it drains down from the left side, moves to the middle, enters the sump cabinet, splits in the middle and drains into each side of my sump. I used a few 90s, a screw attached coupler (forget the name!!), and a couple ball valves for flow control for the fuge side.

 

It will depend on where you overflow line(s) come from (left, right, center, etc.). Mine comes down center, and I just put a "T" right after it comes down, and a ball valve on each side to control how much water goes to each.
