skimmer help

[frankl]

My protein skimmer seems like it is working however the water started to overflow on the outake side. The air hose is not clogged what could be the problem. Please help

when i first set up my ho skimmer, it overflowed also. i needed to adjust the air venturi valve to slow down the amount of bubbles that the skimmer made. once dialed in, it worked fine.
