WORKS PERFECT FOR HOLDING LIVE ROCK TOGETHER TO BUILD GREAT LOOKING AQUASCAPES. Purple color looks like natural coralline within the aquarium. Hardens in about 5 minutes and fully cures after 45 minutes. Combined with our reef glue gel holding just about anything is possible within your reef aquarium.
USAGE TIP: Reef epoxy is not sticky alone or designed to stick to smooth surfaces underwater. It gets it's holding strength by being molded around objects or into crevices in live rock. If you want to "stick" it to a smooth surface underwater or out we recommend putting some reef glue gel on the epoxy then sticking it to a piece of live rock. This will give you the volume void filling of the epoxy with the stickiness of the reef glue.
