Your Choice Aquatics 1.5″ Cement Frag Square Packs – Coral Propagation Tiles

About This Product

The Your Choice Aquatics 1.5″ Cement Frag Square Packs provide a durable, economical, and practical solution for mounting, propagating, and growing coral fragments in saltwater reef aquariums. Featuring a 1.5-inch square cement mounting surface, these versatile coral frag tiles offer a stable foundation for SPS, LPS, Zoanthids, Palythoa, and compatible soft corals.

Available in 1, 15, 25, 50, and 100-piece packs, these frag squares are suitable for everyone from hobbyists maintaining a small coral collection to commercial coral farms managing large-scale propagation systems.

Coral propagation is an essential part of sustainable reef aquarium keeping. By carefully fragmenting established coral colonies and growing them on suitable mounting surfaces, aquarists can expand their collections, develop new colonies, and share aquacultured corals with other reef enthusiasts.

The 1.5-inch square design provides a generous mounting platform for small to medium-sized coral fragments. Compared with smaller round frag plugs, the larger square surface offers additional space for spreading Zoanthid colonies, encrusting Montipora, Chalice corals, and other suitable specimens.

Constructed from cement-based material, these frag squares provide a solid, textured surface for use with reef-safe cyanoacrylate gel and coral mounting epoxy. The surface also allows many coral species to gradually encrust and establish a natural attachment as they grow.

The flat, square profile is particularly useful for organizing coral propagation systems. Frag squares can be arranged neatly in rows, making it easier to identify coral varieties, monitor growth, and maintain spacing between neighboring colonies.

For aquarists growing encrusting SPS corals or colorful Zoanthid gardens, the additional surface area provides room for early colony development before transferring the coral to larger rockwork or permanent display locations.

The availability of multiple package quantities makes these cement frag squares a flexible and cost-effective choice. Small packs are convenient for occasional fragging, while larger bulk packs support frequent propagation, coral trading, and commercial grow-out operations.

Whether you’re building an SPS frag collection, cultivating vibrant Zoanthid colonies, or establishing a dedicated coral propagation tank, Your Choice Aquatics 1.5″ Cement Frag Square Packs offer a dependable foundation for coral growth and organization.

Recommended Applications

SPS Coral Propagation

The 1.5-inch square platform is particularly useful for encrusting SPS species such as Montipora and other corals that spread across solid surfaces.

Branching SPS fragments, including Acropora, Stylophora, Pocillopora, and Birdsnest, can also be secured using suitable coral adhesives.

The broader tile surface provides room for early encrustation and colony development.

Zoanthid and Palythoa Gardens

The square mounting area provides a convenient foundation for small groups of Zoanthid or Palythoa polyps.

As the colony grows, additional polyps may spread across the tile, creating a colorful miniature colony.

Safety Warning: Some Zoanthids and Palythoa contain potentially dangerous palytoxin. Wear appropriate protective equipment, avoid creating aerosols, and never boil or heat these corals or contaminated materials.

LPS Coral Propagation

Certain small LPS coral fragments can be mounted onto these cement squares when their skeletal structure is appropriate for the surface.

Encrusting Chalice corals and other suitable specimens may gradually spread across the tile.

Provide adequate spacing from neighboring corals, especially aggressive species with sweeper tentacles.

Soft Coral Cultivation

Some soft coral species can be propagated using these mounting tiles.

Attachment methods vary by species. Soft corals may require mesh, rubber bands, or temporary rubble containment rather than glue applied directly to delicate living tissue.

Coral Farms and Grow-Out Systems

The square design makes these tiles particularly useful in organized coral propagation trays and grow-out systems.

Larger quantities allow aquarists to prepare multiple coral fragments for cultivation, trading, or retail sale.

Installation and Usage Instructions

1. Inspect and Prepare the Frag Squares

Examine each cement tile for cracks, loose particles, or manufacturing residue.

Rinse thoroughly with clean purified water or prepared saltwater.

Because the exact curing status of this product has not been confirmed, verify that the cement tiles are fully cured before introducing them into an established reef aquarium.

If their curing status is uncertain, condition them separately in water and monitor pH and alkalinity until stable.

2. Select the Coral Fragment

Choose a healthy coral fragment appropriate for the 1.5-inch mounting surface.

Inspect the coral for pests, damaged tissue, and other potential problems.

Use appropriate fragging procedures and protective equipment for the species being handled.

3. Apply Reef-Safe Adhesive

Apply a small amount of suitable reef-safe cyanoacrylate gel or coral mounting epoxy to the desired location on the tile.

Position the coral’s skeletal base or suitable attachment surface against the adhesive.

Hold the fragment securely until the bond begins to set.

Avoid covering sensitive living tissue with excessive adhesive.

4. Position the Mounted Coral

Place the tile on a stable frag tray, compatible rack, grow-out platform, or suitable section of aquarium rockwork.

Ensure that the tile will not shift or fall due to water movement or aquarium inhabitants.

Because these are square tiles rather than conventional stemmed frag plugs, verify that your particular mounting system can accommodate their dimensions.

5. Provide Species-Appropriate Conditions

Position the coral according to its lighting, water flow, and spacing requirements.

Different coral species have substantially different needs. The cement tile itself does not require a particular PAR level or water flow rate.

6. Monitor Growth and Attachment

Observe mounted corals regularly for healthy expansion, tissue attachment, and new growth.

Avoid unnecessary handling while the coral is establishing itself.

When the coral outgrows its mounting tile, transfer it to larger rockwork or a suitable permanent aquarium location.

Maintenance and Care Recommendations

Keep coral frag squares free from excessive detritus and nuisance algae.

Maintain adequate water movement around mounted corals without subjecting sensitive tissue to damaging direct flow.

Inspect neighboring coral colonies for aggressive contact or competition.

Remove damaged or unstable tiles that no longer provide a secure mounting surface.

When reusing a tile, remove old adhesive and biological residue as appropriate, then thoroughly clean and rinse it before introducing a new coral fragment.

Avoid household detergents, soaps, and unapproved cleaning chemicals.

Monitor aquarium pH and alkalinity when introducing significant quantities of cement-based materials, particularly if their curing status is uncertain.
