The IceCap 3/4in Biological Frag Plugs with Mounting Divot (25pcs) are the smallest plug size in the line, sized for tight frag racks or small individual cuttings. The recessed divot gives glue a place to grip, and the porous ceramic construction lets water flow through rather than sitting on a solid surface. Quantity: 25 pieces per bag Best for: Montipora, Zoanthids, Chalices, small SPS colonies, and Euphyllia (torch, hammer, frogspawn) Color: natural tan — blends into reef displays instead of standing out like bright white plugs pH: neutral (7-7.5), safe for reef and mixed systems The smaller 3/4in size is a common pick for high-volume frag swaps and trades, where a compact base matters more than maximum mounting surface.Use with: cyanoacrylate super glue gel (sold separately) for mounting.
