sounds like you might have high do on the water , whats your water chance reign like ? try a water change and see what happens .
 
Possibly high water surface tension as frasertheking was eluding to.

Does the water surface look oily

Is it a planted tank?

Water is your filtering system.

Possible an an air leak on the intake of the filter system.
