1st thing I would do is to dismantle & clean all the parts. Then try again.

You can also test it in a pail of water to see if the same issue persist.

Seek advise from LFS where you purchased from, especially if it's still under warranty.

I hv alrdy dismentle and clean all the parts.Run the skimmer on another small tank with different water level still the same.Call the LFS and told me need few days for skimmer to break in.Is it normal for new skimmer with water level unstable cos so far i never encouter new skimmer with unstable water level
