Maxspect Coral Putty is a 100% reef-safe coral adhesive available in a 120g package. This underwater-friendly putty is colored to match coralline algae, ensuring seamless blending with aquarium surroundings. Formulated as a two-part silicone-based compound, it sets in just 3 minutes without emitting foul odors or clouding the water. Unlike traditional adhesives, it won't cause protein skimmer overflow. Suitable for both marine and freshwater aquariums, it's ideal for securing corals and other aquatic décor. Its coloration facilitates discreet application, and since most corals grow over it within weeks, minimal usage is recommended.
