IceCap Medium PRO 23-Hole Magnetic Coral Frag Rack (IC-FR23R)
The IceCap Medium PRO 23 Coral Frag Magnetic Rack (SKU: IC-FR23R) is an authentic, premium livestock propagation shelf distributed by CoralVue to provide marine aquarists with an elite, secure environment for fragment grow-out and light acclimation. Standard traditional egg-crate styles or generic clear plastic acrylic shelves often present frustrating design challenges: they slide down your glass pane under the heavy weight of growing corals, trap dense detritus pockets underneath, and allow active snails or wavemaker flow bursts to tip plugs over, landing expensive coral tissues upside down in the sand bed. The IceCap PRO Series eliminates these propagation headaches by integrating an active structural security system directly into the shelf plate.
The core breakthrough of the PRO 23 rack is its integrated Flexible Stem-Gripping Membrane. Rather than relying on simple, oversized drilled holes, every port features an elastic internal membrane liner. This layer flexes to accommodate various commercial plug stems up to 3/8-inch (∅3/8in) in diameter, pinching them securely in place so they remain upright even when brushed by large grazing fish or cleaner crews.固定 Crafted from robust, marine-safe solid black acrylic, the shelf naturally hides equipment shadows and prevents light transmission from feeding hair algae colonies underneath. Backed by heavy-duty, epoxy-coated external magnets, the rack locks onto display panels or sump glass up to 1/2-inch thick, offering a dependable platform for your high-value stony corals or zoanthid colonies.
Key Features
Locks Plugs Firmly in Position: Elastic inner lining stops Turbo snails, sea urchins, and high-velocity water movement from dislodging your frags.
Promotes Fluid Water Exchange: Clean, open-shelf engineering allows uniform aquarium flow lines to pass over, around, and beneath coral bases to prevent tissue stagnation.
Safe, Multi-Tiered Acclimation Tool: Allows you to position newly purchased coral frags near the bottom of your display glass and gradually raise the shelf over time to acclimate them to high-output LED fixtures.
(Note: This retail box includes (1) Medium PRO 23-hole black acrylic frag shelf plate, (1) wet-side internal magnet bar, and (1) dry-side external magnetic backing block. Coral frag plugs, discs, and coral glues are sold under separate product categories).
