Micro bubble from the water return

[Wes888]

Hmm.. Just upgraded my Quiet One 4000HH to a 6000 and changed the plastic tube from a 3/4" to a 1". Lot of flow but there are micro bubble coming out. Any particular part that I didn't tighten enough? What might have caused it?

nvm. It's the in-sump protein skimmer producing the micro bubbles. My sump doesn't have a separate compartment for protein skimmer and it has to share the room with the return pump. My guess is that the bubbles were kinda minimal and always there. With the slower pump, the bubble were dissipated before it got to the pump. With this new pump, the sump looks like a river. Lots of micro bubble were sucked out from the skimmer.
