I installed a CS6-2 nearly 2 weeks ago in a 90 gal. reef. Finally am producing some foam and was wondering where other users keep the water level at? More specifically the interface between the foam and the rising bubbles. I currently have the adj. riser set so that the line betwwen the actual foam and the rising bubbles is about 1" down from the top of the tube within the collection cup. My sump level is 7" and bioload is relatively light. I have read that some users keep the riser all the way down but when I tried lowering it the foam never gets up into the cup.
Thanks,
