Coral Frag Disks

Oceans Wonders Coral Frag Disks are perfect for corals that may show the frag disk under after it grows. Corals like chalices, favia, acans, and more will benefit from the round disk as it matches the circular growth pattern of the coral. Compared to frag tiles, round disks do not have the same surface area but do offer a more natural shape if mounting onto your rock structure may be required.  

Three Sizes Available:

• 1" (20 Pack)
• 2" (10 Pack)
• 3" (10 Pack)

Oceans Wonders Coral Frag Disks are made with a special grade white reef sand that is fused together. The natural calcium based sand helps encourage the spreading of corals and coralline algae. We do suggest curing all non-ceramic frag disks for the best results.
