in my 55gal i have a under gravel jet system. i recently added a bubble wand to my tank in the back, buried it under the gravel but the question i have is the power head that i have rinning my UGJ system is sucking in some of the air from the bubble want, mind you it looks cool i have little random streams of bubbles coming out of my gravel but i am wondering if it is bad on my powerhead. i know they have they have the venturi system but that air is sucked in after the water has ran through the pump.
