Aqua Medic Coral Pins are specialized stainless-steel pins designed for properly anchoring corals, frags, and small rock formations in marine and reef aquariums. Ideal for aquascapers and reef keepers, these pins allow secure attachment without damaging delicate coral tissue or disrupting the layout. Their corrosion-resistant construction ensures long-term durability in saltwater environments, while their slim profile helps maintain a natural look once planted. Using Aqua Medic Coral Pins helps create stable, organized coral structures and promotes healthy growth by preventing coral pieces from shifting or falling — essential for stable reef setups and frag racks.
