Your Choice Aquatics 1.75″ Cement Frag Disc Packs – Coral Propagation and Mounting Discs
About This Product
The Your Choice Aquatics 1.75″ Cement Frag Disc Packs provide a durable, economical, and versatile solution for mounting, propagating, growing, and displaying coral fragments in saltwater reef aquariums. Featuring a generous 1.75-inch round cement mounting surface, these coral frag discs offer an excellent foundation for SPS, LPS, Zoanthids, Palythoa, and compatible soft coral species.
Available in convenient 25, 50, and 100-piece packs, these frag discs are ideal for individual reef enthusiasts, dedicated coral collectors, aquarium retailers, and commercial coral propagation facilities.
Coral propagation is an important part of sustainable reef aquarium keeping. By carefully dividing established coral colonies and mounting healthy fragments on suitable surfaces, aquarists can grow new colonies, expand their collections, and share aquacultured corals with other hobbyists.
The 1.75-inch diameter provides additional room for coral growth compared with smaller frag plugs and discs. This larger mounting area is particularly beneficial for encrusting Montipora, Chalice corals, Zoanthid colonies, and other specimens that gradually spread across solid surfaces.
Constructed from cement-based material, these discs provide a solid mounting foundation compatible with reef-safe cyanoacrylate gel and suitable coral mounting epoxy. The cement surface allows many coral species to establish a secure attachment and gradually encrust across the disc as they grow.
The round design makes these discs useful for organized coral propagation systems, where individual fragments can be arranged, inspected, and repositioned according to their lighting and water flow requirements.
For branching SPS corals, the wider base provides additional mounting area for securing fragments. For encrusting species, it offers room for developing colonies before they are transferred to permanent aquarium rockwork or larger grow-out surfaces.
The availability of bulk packaging makes these discs especially convenient for aquarists who regularly propagate corals. The 25-count pack works well for smaller projects, while the 50- and 100-count options provide additional supplies for active frag tanks and commercial coral cultivation.
Whether you’re developing colorful Zoanthid gardens, growing premium SPS fragments, propagating Chalice corals, or preparing corals for trading and resale, Your Choice Aquatics 1.75″ Cement Frag Disc Packs provide a dependable foundation for coral growth and organization.

Recommended Applications
SPS Coral Propagation
The 1.75-inch cement frag disc provides an excellent foundation for both branching and encrusting SPS corals.
Small Acropora, Montipora, Birdsnest, Stylophora, and Pocillopora fragments can be mounted using suitable reef-safe adhesives.
The larger disc surface allows room for initial encrustation and supports the development of young coral colonies.
Zoanthid and Palythoa Gardens
The wider mounting area makes these discs particularly useful for growing Zoanthid and Palythoa colonies.
Individual polyps or small clusters can gradually spread across the surface, creating attractive miniature coral gardens.
Safety Warning: Some Zoanthids and Palythoa may contain dangerous palytoxin. Wear appropriate protective equipment, avoid creating aerosols, and never boil, heat, or pressure-wash these corals or contaminated materials.
LPS Coral Mounting
Certain small LPS coral fragments, especially encrusting varieties such as Chalice corals, may benefit from the additional surface area.
Secure the coral’s skeletal base using suitable reef-safe adhesives and provide adequate spacing for future growth.
Corals with large fleshy polyps or extensive skeletal structures may require larger mounting surfaces.
Soft Coral Propagation
Compatible soft corals can be mounted using species-appropriate techniques.
Some soft coral varieties attach more successfully when temporarily secured with mesh, rubble containment, or other gentle methods rather than adhesive applied directly to living tissue.
Commercial Coral Grow-Out Systems
The 50- and 100-count packages are particularly convenient for coral propagation facilities, aquarium stores, and reef enthusiasts who regularly produce coral fragments.
The discs help organize coral collections, monitor individual growth, and prepare established specimens for trading or resale.
Installation and Usage Instructions
1. Inspect and Prepare the Frag Discs
Inspect each cement disc for cracks, loose particles, or manufacturing debris.
Rinse thoroughly with purified water or prepared saltwater before use.
Verify that the cement material has been fully cured before introducing the discs into a reef aquarium.
If the curing status is uncertain, condition the discs separately and monitor water pH and alkalinity before installation.
2. Select Healthy Coral Fragments
Choose healthy coral fragments appropriate for the available mounting area.
Inspect each fragment for damaged tissue, pests, and other potential problems before mounting.
Follow appropriate fragging and handling procedures for the individual coral species.
3. Apply Reef-Safe Adhesive
Apply a small amount of reef-safe cyanoacrylate gel or suitable coral mounting epoxy to the disc.
Position the coral’s skeletal base or appropriate attachment surface against the adhesive.
Hold the coral securely until the bond begins to set.
Avoid applying excessive adhesive directly to sensitive living coral tissue.
4. Position the Mounted Coral
Place the frag disc in a stable propagation tray, compatible disc holder, or suitable area of aquarium rockwork.
Ensure the disc cannot slide, tip over, or become dislodged by water movement or aquarium inhabitants.
Because these are round discs rather than stemmed plugs, verify compatibility with your particular frag rack or holder.
5. Provide Appropriate Lighting and Flow
Position each coral according to its specific lighting, water circulation, and spacing requirements.
Different coral species have different environmental needs, and the frag disc itself does not determine the required PAR or flow level.
6. Monitor Coral Growth
Observe the coral regularly for tissue expansion, attachment, and new growth.
Avoid unnecessary handling while the coral is establishing itself.
As the coral develops beyond the available mounting area, transfer it to larger rockwork or an appropriate permanent display location.
Maintenance and Care Recommendations
Inspect mounted frag discs regularly for nuisance algae, accumulated detritus, and unwanted organisms.
Provide adequate water circulation around growing coral fragments without exposing sensitive species to damaging direct flow.
Maintain sufficient spacing between neighboring colonies to prevent aggressive contact or tissue damage.
Replace discs that become cracked, damaged, or unstable.
When reusing a disc, remove old adhesive and biological residue as appropriate, then clean and rinse it thoroughly before mounting another coral.
Avoid household detergents, soaps, and unapproved cleaning chemicals.
Monitor aquarium pH and alkalinity when introducing large quantities of cement-based mounting products, particularly when curing status is uncertain.
