Looks great,
May be only me, but i like better first pics, were start with Pukany, those rocks hold a tremendous amount of Bacteria , also , those Gyro pumps was better in first option, push water under the rocks and end up right on overflow box, remove Detritus faster and more efficient , have it on sides skip the overflow . Those flat shape of Marko Rocks will hold up lots of Detritus , needs to be blow constant. Anyway is your choice , tank looks great , no matter what.:party:
