Quantum Large Standard Frag Plug 50 Pack — 32 mm Ceramic Plugs for Bigger Coral Fragments and Colonies
A standard 20 mm plug is fine for a fresh acropora tip, but a hammer head or a fist-sized zoanthid rock needs a base that will not tip under it. Quantum Large Standard Frag Plug 50 Pack (SKU: QA700250) gives you fifty Reef Essential plugs with a 32 mm disc on a 10 mm stem, wide enough to carry a mature frag or a small colony and still drop into a standard rack hole. The disc face is textured for glue and tissue, and the ceramic is ICP-OES analysed so it goes into the tank without curing.
The larger disc changes how a rack behaves. Heavier LPS frags stop rocking when a wavemaker sweeps past, encrusting corals get months more growing room before they reach the edge, and a mounted piece looks proportionate rather than perched. The stem is the same 10 mm as the regular plug, so both sizes share the same holders and the same egg-crate. Fifty in a pack suits keepers who frag LPS regularly, sell or swap colonies, or simply prefer to mount everything on a base that will not need replacing as the coral grows.
Usage & Application
When to Use
- LPS fragments: Euphyllia heads, favia and acan chunks sit stable on a 32 mm disc where a small plug would tip.
- Small colonies: Mounting a whole zoanthid or mushroom cluster on one base rather than splitting it.
- Grow-out for encrusting corals: The wider face delays the day a spreading coral outgrows its plug.
- Display mounting: A proportionate base for pieces that will be glued straight onto rockwork and left to encrust over the disc.
How to Use
- Use immediately: No curing or soaking; rinse in tank water if you prefer.
- Dry, then glue: Blot the disc and the coral base so the adhesive grips the textured ceramic.
- Support heavy pieces: For large LPS heads, a ring of epoxy around a bead of glue holds while the tissue takes.
- Rack or rock: Seat the 10 mm stem in a rack hole, or snip it off and glue the disc flat onto rock once the coral has settled.
Product Specifications & Highlights
Key Features
- 32 mm disc: Roughly two and a half times the surface area of a 20 mm plug, for bigger frags and small colonies.
- Standard 10 mm stem: Fits the same racks and holders as the regular Quantum plug.
- ICP-OES analysed: Batch-tested for contaminants before it reaches a reef.
- No curing required: Ready to mount the day it arrives, with no soaking or pH-settling period in a bucket.
- Textured surface: Gives glue and coral tissue a secure grip, so heavier frags stay put in flow.
