Good diagrams for closed loop, etc..??

[Aquabucket]

I have been using the search feature on here an Google and still can't find some good diagrams explaining closed loops and other plumbing options for a reef tank.

Anyone here can point me to some good info?

Thanks ia,

Here's a photo with info of my closed loop system. The returns at the tank ends are split into two and have lock-line tubing with end nozzles for directional aiming. All lines are 1" flex pipe. Hope this helps.
