Ive tried both pushing and pulling from the reactor with the same result. I put a maxi jet back on the feed and it solves the issue. Any ideas?

Shut the circulation pump off on the Geo. Shake the reactor side to side to get the bubbles to the top and then hit and hold the prime button. That will vacuum all the bubbles out of the reactor. You can wobble the reactor a bit more to get any remaining air that may be trapped in the media out.. Also, helps to guide the bubbles to the top hole in the reactor in the event that the floor isn't perfectly level. With my Geo, I found it was best to push the water into the reactor via the Masterflex instead of pulling.
