Available Through Authorized Retailer
- Integrated Center Mounting Divot: Formed with a specialized center indentation pocket that puddles cyanoacrylate gel glues and cradles freshly cut branching stalks to prevent tipping.
- Fused Nano-Sphere Architecture: Manufactured from high-purity ceramic micro-beads bound at high temperatures, creating a deeply interconnected network of microscopic flow channels.
- Integrated Universal Anchor Peg: Features a standard-diameter molded bottom stem that slots securely into commercial acrylic frag racks, magnetic carriers, and standard light-crate grids.
- Superior Adhesive Bonding: The rough, textured surface profile maximizes the mechanical grip of cyanoacrylate frag glues, preventing loose frags from tumbling down.
- 100% Inert and Cure-Free: Completely free of heavy metals and pollutants, requiring no lengthy freshwater curing cycles or chemical pre-washes before tank introduction.

IceCap 3/4 Inch Biological Ceramic Nano-Sphere Coral Frag Plugs with Mounting Divot
The IceCap 3/4 Inch Biological Ceramic Nano-Sphere Coral Frag Plugs with Mounting Divot (SKU: IC-BFP25-D) represent a major technical advance in marine coral propagation substrates, designed specifically to accelerate tissue encrusting speeds and enhance localized water chemistry parameters. Standard dense aragonite mounts or smooth compressed-clay discs offer only basic two-dimensional surface areas. This forces expanding coral tissues—such as Acropora, Montipora, Chalice, and colonial Zoanthids—to expend precious metabolic energy trying to grip a slick surface. The IceCap biological plug completely bypasses this growth bottleneck, providing an advanced three-dimensional matrix of fused ceramic nano-spheres that mimics the natural porous microstructure of wild reef frameworks.
By fusing thousands of microscopic ceramic beads under precise heat tracks, each 3/4-inch plug opens up an internal labyrinth of capillary pathways. This specialized divot configuration features a small center indentation molded directly into the crown. When fragging branching small-polyp stony corals (SPS) or small large-polyp stony (LPS) fragments, this divot acts as a structural pocket that contains your cyanoacrylate gel glue, preventing messy run-off while mechanically anchoring the base of the cutting upright. This highly porous structure allows vital, oxygen-rich tank water to sweep directly through the base of the plug. This action eliminates stagnant oxygen-starved zones and distributes dissolved elements cleanly to the coral's base. At the same time, this high-flow web becomes an immediate sanctuary for populations of beneficial nitrifying and denitrifying bacteria (Nitrosomonas and Nitrobacter). As a result, each coral frag you position across your racks doubles as a highly active block of bio-media, which helps actively lower organic waste and ammonia levels throughout your system.
Key Features
Molded Center Indentation: Deepens mechanical stability for newly cut stalks, positioning the tissue securely against the glue pocket to minimize lateral displacement.
Universal Stability Peg: The molded bottom stem keeps your newly sliced frags oriented upright and secure against strong powerhead flow and clean-up crew movements.
Inert, Non-Leaching Chemistry: Kiln-fired to ensure complete chemical neutrality. These bases will not trigger unwanted local hair algae outbreaks or warp your water's pH balance.

While most of our equipment carries a one-year manufacturer's warranty, consumable products like fish and coral foods are not covered under traditional warranty terms due to their perishable nature and varied storage conditions. However, we fully stand behind the quality of every product we sell. If you experience any issues with your food purchase shortly after receiving it, such as concerns about freshness, packaging integrity, or product quality, please contact us at [email protected]. We're committed to making it right and will work with you to resolve any problems quickly and fairly.
- Remove the desired number of divot biological frag plugs from the packaging box. Give them a quick rinse in a cup of clean reverse osmosis (RO) water to remove any loose ceramic dust from shipping.
- Prepare your source coral colony on a clean cutting mat, using specialized stainless steel bone cutters or an aquaculture band saw to slice clean coral fragments.
- Apply a small droplet of gel-type cyanoacrylate coral frag glue directly into the center mounting divot pocket of the plug.
- Lightly dry the bottom raw tip of the coral fragment with a clean paper towel, then seat the stem end firmly into the glue-filled divot. Hold it in position for 10 to 15 seconds until the adhesive sets.
- Place the completed frag into a container filled with clean tank water or a mild coral dip solution for 3 to 5 minutes to fully cure the glue before adding it to your display.
- Slide the plug's stem into your designated frag rack, eggcrate grid, or magnetic mount. Ensure it receives proper indirect flow and lighting tailored to that specific coral species.
Pro Tips:
- The Center Divot Controls Gel Migration Perfectly.
CRITICAL FRAGGING ADHESIVE WARNING: The built-in mounting divot is specially engineered to lock the adhesive footprint down into a centralized pocket. Because the fused nano-sphere matrix contains thousands of open micro-pores, capillary action will draw the base of the glue drop deep into the walls of the pocket. Use only enough glue to fill the floor of the indentation; over-filling will cause glue to climb the stalk and smother living coral polyps.
- Pre-Soak Your Plugs in an Internal Sump Track to Jumpstart Cycling. If you are planning a large fragging project, drop a handful of these biological plugs into a high-flow chamber of your sump a couple of weeks before you use them. Because they are incredibly porous, they will quickly collect a rich layer of active nitrifying bacteria straight from your system. When you attach your new coral fragments, this pre-established bio-layer helps protect the cut tissue from opportunistic infections and accelerates healing times.
- Clean Calcified Mineral Scale and Algae with a Mild Vinegar Soak. If you have used plugs sitting on your racks that have collected a layer of green turf algae or calcified tube worm scale, do not throw them away—they are fully reusable. Simply soak the fouled plugs in a bath of warm water mixed with 10% white vinegar for 24 hours to dissolve the mineral scale. Rinse them thoroughly with fresh RO water and let them dry completely in the sun for 48 hours. This clears out the pores and restores them to factory-new condition.
