What kind of adhesive can you use in a saltwater aquarium?

Cyanoacrylates, also known as super glue, are commonly used in saltwater aquariums. They provide a quick and strong bond that can withstand the saltwater environment. However, it's essential to choose a cyanoacrylate specifically formulated for aquarium use, as some products may release harmful fumes or chemicals into the water. Two-part epoxy adhesives are another popular choice for saltwater aquariums. These adhesives offer a strong and durable bond but require mixing two components before application. Silicone adhesives can also be used in certain situations, but they are not as water-resistant as cyanoacrylates or epoxy adhesives.
