Yes 8x2x2. And yep you got it from the air pump to the power head. I am going to add another 400 and another canester later but right now I am shuffiling my collection around and making room for the big tank. I gave away two pairs of CIchlids the Bredohri ad the Cuban Tetracanthus to make more room and get rid of some of my smaller usless unecessary tanks.
