powerhead making bubbles

[rcranf]

my powerheads stirs the water up to make an tidal wave and then sucks the water through causing alot of airbubbles and such. Is this a bad thing for the tank or is it ok.
I have a 125 gallon cornerflow tank

Sounds like it's sucking air. Air bubbles not good for a SW tank.

Depends on how powerful the motors on them are, but probably 2-3", until it can't suck a funnel up to the surface and grab air.
