I am using a Mag 7 pump for my return in to a 55 gal tank. I do have very minute bubbles probably 1/4mm coming out of the nozzle that makes the visiblity a little less than perfect. Is this normal? I made sure that there is very little turbulence at the inlet of the return pump but still get these small bubbles.
