Description
AquaStik Underwater Epoxy Putty in Coralline Red is a reef-safe adhesive designed for marine and reef aquariums. Originally produced by Two Little Fishies, this epoxy putty blends well with coralline algae and live rock, making it less conspicuous in aquascapes. It is easy to mix and cures reliably in dry, damp, or underwater environments. Because of its quick setting nature, only small amounts should be mixed at a time, and many reef keepers prefer to use the minimal quantity since over time corals tend to grow over the adhesive surface.
AquaStik is frequently used for coral fragging, aquascaping, and securing stony corals, gorgonians, or aquatic plants. It bonds not only to porous rock but also adheres to a variety of materials including glass, concrete, ceramics, acrylic, metals, and fiberglass, allowing versatile use in aquarium setups.
