I have a pump that sits in my sump to return water to my display tank but I get small little bubbles coming from it. I have tried a prefilter on the intake of the pump, a second utube on my overflow box, Changing the the tubing. The tubing is secured by metal hose clamps and the water level is good???? Any imput would be great.... Thanks!
