Bubble trap
Hello,
A variety of ways to reduce bubbles,
1) Attach an elbow in the skimmer chamber to the drain, with the inlet of the elbow pointing down.
2) Close your gate valve so air/water interface rise a bit higher.
3) Raise the drain above water level.
4) Place baffles in sump.
5) Allow water to pass through high porous (low density) foam or bio-balls.
