A porous ceramic frag plug gives new coral tissue something to actually grow into rather than just sit on top of, and IceCap's biological plugs come in four sizes and top styles to match different coral types and frag rack setups.
Why Porous Ceramic Over Solid Plugs
Solid plastic or resin plugs give coral tissue a surface to attach to, but a porous ceramic plug lets tissue actually grow into the material itself, generally producing a stronger, more natural-looking base as the frag matures.
Choosing a Size and Top Style
- 3/4in Biological Frag Plugs with Mounting Divot (25pcs) - the smallest plug size in the line, sized for tight frag racks or small individual coral pieces.
- 7/8in Biological Frag Plugs with Flat Top (25pcs) - sits between the 3/4in and 1in sizes, a slightly larger flat mounting surface.
- 1in Biological Frag Plugs with Mounting Divot (25pcs) - adds a small recessed divot to the top of the porous ceramic plug, giving glue somewhere to key into.
- 1in Biological Frag Plugs with Flat Top (25pcs) - the same porous ceramic-sphere construction in a flat-top format for corals that mount better on a level surface.
Divot vs. Flat Top
A mounting divot gives glue a recessed spot to key into, useful for smaller or irregularly-shaped frags; a flat top suits corals that naturally sit better on a level mounting surface.
