Refugium Water Source
I have a 50g tank with a 20g sump with refugium and would like to know if it is better to supply the refugium from one of the overflows or tee off from the return pump. I have a Mag 9.5 at the moment and had to throttle the discharge down about 50% to get rid of the micro bubbles. If I teed off from the pump could I increase the flow rate without getting bubbles or is the flow rate already sufficient? Thank-you!

I think that's what I'll do. I put one valve on one of the drains to direct some flow into the refugium but it looks like I'll have to add another after this valve as not much seems to be actually getting to the refugium.

On mine, the valve on the downward leg controls the flow to the sump (and therefore amount diverted to fuge).
The horizontal valve does nothing for flow control and is only there so I can isolate the fuge.

That is basically what mine will look like as well. Thank-you for the picture!

The outlet from your refugium to your main tank is gravity feed and located near the top of the refugium, provided that your refugium is higher than your main tank. The purpose of the refugium is to provide a super breeding ground for pods and other critters(without predators in it) and provide a space for macro to grow to assist in removing nitrate from you system. Pods and critters eggs flow undisturbed without a pump into your main tank.
