1" Biological Frag Plugs with Flat Top - 25 Pack

IceCap 1" Biological Frag Plugs with Flat Top - 25 Pack

The IceCap 1" Biological Ceramic Nano-Sphere Flat Top Coral Frag Plugs 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 Montipora, Chalice, Acan, 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 1" flat-top plug opens up an internal labyrinth of capillary pathways. While alternative plugs contain deep central divots that can restrict placement to single vertical branches, this specialized flat-top configuration offers a level surface area. This ensures that encrusting plates or clustering soft tissue colonies can spread evenly without falling into deep hollows. 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.

Features:

• Level Flat Surface Optimization: Offers an unmarred surface area for cleanly applying glue lines and securing wide fragments, branching stalks, or sprawling soft colonies.
• 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.

Specifications:

• Plug Crown Nominal Diameter: 1" (25.4mm Top Profile Face)
• Plug Stem Configuration: Integrated Molded Anchor Peg (Fits Standard 3/8" Grid Slots)
• Primary Material Matrix: Kiln-Fired Fused Synthetic Ceramic Nano-Spheres
• Porosity Value Rating: Greater than 65% Open Interconnected Volumetric Porosity
• Curing Cycle Required: 0 Days (Factory Cured, Inert, Direct-to-Tank Safe)
• Primary Structural Color Finish: Earthy Speckled Charcoal / Light Brown Matrix

Instructions:

1. Remove the desired number of flat top 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.
2. 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.
3. Lightly dry the bottom surface of the coral fragment with a clean paper towel. Apply a small bead of gel-type cyanoacrylate coral frag glue to the center of the plug's flat surface.
4. Press the coral fragment gently down into the glue pool on the flat top face. Hold it firmly in position for 10 to 15 seconds to let the adhesive establish a strong mechanical bond within the ceramic pores.
5. 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.
6. 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:

• 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.
