I am completely lost.. I have tilted it, turned it on, taken filler port off, tilted it so the bubbles get in the reservoir, sucked out the bubbles and repeated those steps, the bubbles come back, infinitely. There is no problem with the CPU loop whatsoever, its just the GPU loop. How do i empty my GPU loop? Because that seems to be the only options as there MUST be something wrong with the water. The CPU water looks completely clear, while the GPU water has some more of a milky look. Ideas?
