I recently added a media reactor to the back chamber of my Waterbox Cube 20. I am now having issues with the pump running dry. I think the water doesn't flow to the pump quick enough and the return chamber keeps getting drained. I just ordered another pump with a lower gph
rating. I plan to add a skimmer and maybe a second reactor with a different media so I know this is going to be an ongoing issue. Is there something I can do to increase the flow in the back? Add a circulation pump or something else?
