so for weeks now my skimmer has been acting funny.i clean it out and make sure the air intake is always free of being clogged but it bubbles over.the only thing that us different is the stand that was built gets no good air flow.i do have 4 vents but it still gets stuffy.i was thinking of adding a long air intake line to outside of stand.will this affect performance of skimmer.do you think lack of air might be causing the this to happen.its not anything that im adding to tank thats making it bubble over.
