Salt, Sand, Rocks
Since live rock has become difficult to import, many reefers have turned to dry aquarium rocks, like marcorocks, to aquascape their tank. Some Marco rocks are quarried from ancient dry reefs. Several companies now make artificial live rock, some of which comes with beneficial bacteria seeded into the dry rock. These new alternatives to wild harvested live rock don’t harm living coral reefs. In addition, with aquarium dry rock there is no danger of dangerous reef hitch hikers entering your tank.
