The Alternative Reef Donuts are ceramic pieces that are great for growing out larger corals like leathers, zoanthids, lps and sps. It has a hole in the middle that can be fitted with a small piece of rock or coral frag. Plugs and disks also fit in the hole. It is also a nice alternative to rubble rock. Some hobbyists do not like using frag plugs or disks. They prefer the more natural look of the donut. Once it corallines up and the coral encrusts over it is hard to tell that it is artificial. They can be stored dry and unlike rubble does not need to be stored in a sump.
