Using a ¼†fiber glass rod, drill ¼†holes and ( shish kebob ) “Souvlaki†the rocks. Easy coral removal and placement after drilling the rocks with a frag plug hole ½†advantage over other rock formations such as more water movement, can stock corals all the way up for more light “penthouse†and others. I may be the inventor of this method :nerd:
It can also be used in an algae scrubber for more surface area and better water movement. :tongue:
