overflow tube bubbling

[caomt]

anyone ever having problems with their overflow to overflow tube bubbling in sump?

the tube coming from the prefilter will always bubble in the sump because there is some air getting caught in the water while it comes down.

Try to straighten your tubing. Air bubbles will go up. They maybe getting caught somewhere in the hose. Then they get to big then it floats up. Try to correct your hosing.
