1" Biological Frag Discs - 25 Pack

1" Biological Coral Grow-Out Frag Discs

IceCap's 1" Coral Frag Discs feature a dense arrangement of small ceramic spheres that create an optimal mounting surface for coral propagation. The compact disc format is perfectly sized for individual coral frags and smaller colonies.

These versatile discs are ideal for fast-growing species like Montipora, Zoanthids, and Chalices, while also providing an excellent biological foundation for small SPS colonies. They work equally well as secure mounting bases for Euphyllia corals, including torches, hammers, and frogspawn.

Coral attachment is quick and reliable using cyanoacrylate super glue gel (sold separately) for professional propagation results.

Why Biological Frag Plugs are Superior to Traditional Plugs:

• Enhanced Coral Bonding - Porous ceramic sphere construction provides superior surface area that encrusting corals can naturally bond to, creating stronger, more stable attachments.
• Improved Water Flow - Porous design allows water to flow freely through the plug, unlike solid traditional plugs that restrict circulation.
• Healthy Bacterial Colonization - Increased surface area promotes beneficial bacteria growth without affecting pH levels.
• Natural Aesthetics - Natural coloration blends seamlessly into reef displays, eliminating the unsightly bright white contrast of traditional plugs.
• Reduced Algae Growth - Natural color reduces algae promotion compared to bright white traditional plugs that can become an eyesore.
• True Porosity - Unlike traditional plugs that may have surface texturing but remain solid and non-porous, biological plugs offer genuine porosity throughout.
