So I have taken over my dad's 90 gallon fish tank which has a 30 gallon sump. The pump is having little air bubbles coming out of it and the water level in the sump is above where the pump level is and just can't seem to get them to go away. Unless I unplug the pump then let the water in the sump rise the turn it back on for a little while no little bubbles. Any suggestions will help. here are pics to help paint a pic
