Help with loop.

I'm probably not the best person to give advice because I haven't yet completed my loop just yet, but what I've read is that you need to make sure your loop is completely full. If you can still fit water in, keep putting in water. Once that's done, you'll need to pulse the system. As in, have the motor on the slowest speed, then pulse it up to the fastest, and keep doing this. While pulsing, try tilting your PC back and forth as well.

Completely full? You sure about that? I see pics of other peoples setup's with res not full either. Does height above res matter?

As far as I know bay reservoirs take a heck of a long time to get all the air bubble to bleed out... so it could be recycling the air bubbles in the reservoir.

Your main problem is your pump location. Pumps are best placed in the lowest part of your system. Do you have a bleed screw on your top Rad?
