1in Biological Coral Grow-Out Frag Disc 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.
