flow problems with My fx5

[pjegues]

I spoke too soon, when I woke jup this morning the fx5 was maiking that sound again. I can't think of what it could be, its definitly not leaking water on the floor and the inlet is way beneath the surface of the water. That being said where could this air be coming from?

do u use a polishing pad in the middle of the baskets if so remove them this happens with them all the time leave the middle baskets for bio media and the side sponges use them only trust me after some time the middle sponges in the center from all the pressure flatten out to the point where they slow down you flow it happened to me on both of my fx5's i dont use them just on the sides

I don't have any polishing pads but I do have some bio media thats in a fine mesh filter bag in the center of the middle tray. I'll check that out in an hour or so.
