All I can think of is mechanical filtration to calm these bubbles down. I put a ball valve on each line to take as much air out of line as I could but there are so many bubbles in the display. I tried filter floss in between the last set of battles but that slowed my water flow down too much and a man ATO kick on unnecessarily. I have the square bracket for filter socks but don't know where to get socks to fittit.
