I have the 125 model coral life ss and I turned it off for a few days and when I went to start it back up I have a problem with a ton of micro bubbles. It is set up as a HOB of my sump and it has the bubble diffuser but the water is just overflowing and creating bubbles going to my sump, then the rtn pump, and into my display tank. Any one have one as well and know of any tricks to get this set right? I was playing with the dial but the slightest move was making pretty drastic changes in the level of the bubbles in the collection cup and I can't get it set back up right. Thanks in advance.
