The extra thick gel super glue has excellent quality and is one of the easiest glues to use.

It is 100% reef safe and perfect for attaching corals to frag supports or aquascaping with rocks and other materials. Extra thick gel superglues are chosen because they hold their shape and hold up better than regular superglues, allowing them to work well for holding together fragments underwater or better holding larger fragments, such as acropora branches, and filling in gaps where more liquid glues would simply clump up.
