I find myself buying ‘boulder’ rocks when I feel like my aquascape needs a shake up. I use a flathead screw driver and a hammer to break it up (using the chisel technique) and I create stuff (mostly arches) or just spread the rubble so my Zoa beds have a little up and down action as they grow over the rubble. Also makes fragging a breeze
