HeXiDiscs FAQ

Created by Adam Clayton, Modified on Wed, 8 Apr at 10:40 AM by Adam Clayton

What are HeXiDiscs?
HeXiDiscs are hexagonal coral frag mounts made from high-purity aragonite (Xport-Ca), designed for efficient coral placement and growth in marine aquariums.


What do HeXiDiscs do?
They provide a stable surface for attaching coral frags while maximizing usable space in grow-out systems through their hexagonal, honeycomb-style design.


What makes HeXiDiscs different from standard frag plugs?

  • Hexagonal shape allows tight placement with minimal wasted space
  • Higher surface area compared to round plugs
  • Designed for more efficient coral farming and grow-out systems

What are HeXiDiscs made of?
They are made from a porous, aragonite-based material (Xport-Ca) that mimics natural reef structure and supports biological activity.


Do HeXiDiscs provide biological filtration?
Yes. Their extremely high surface area supports colonization of beneficial nitrifying bacteria, which helps stabilize nutrient levels in the system.


What types of corals can be grown on HeXiDiscs?
They are suitable for:

  • SPS (branching and plating corals)
  • LPS corals
  • Soft corals
  • Zoanthids and colonial polyps

Why use HeXiDiscs instead of traditional plugs?

  • Maximizes space in frag tanks or grow-out systems
  • Encourages faster coral growth due to increased surface area
  • Allows cleaner, more organized layouts
  • Reduces wasted gaps between frags

How do I use HeXiDiscs?

  • Rinse briefly in aquarium water before use
  • Dry the attachment area slightly
  • Use reef-safe glue to attach coral
  • Place in the aquarium once secured

Can I leave HeXiDiscs in the tank before using them?
Yes. They can be placed in the system ahead of time to seed with beneficial bacteria and coralline algae.


Will HeXiDiscs blend into the aquarium over time?
Yes. They will gradually become covered in coralline algae and blend naturally with live rock.


Can HeXiDiscs break?
They can break if dropped or mishandled, but can typically be repaired using reef-safe adhesive.


What problems do HeXiDiscs help solve?

  • Inefficient use of space in frag systems
  • Corals being too spread out
  • Slow grow-out due to limited surface area
  • Poor frag organization
