Orca underwater glue from Aquarium Munster is what you might expect from a sealing agent. Unlike other glues, this one can be used in the water. Whereas other products need the area you are applying the glue or solvent to be dry or free from water this isn’t so with Aquarium Munster’s newest product. The Orca underwater glue is free of solvents, isocyanates and silicones, which means that your fish and corals won’t die if you decide to use the stuff in your tank. Now granted, we really wouldn’t suggest using this unless you have a leak and odds are if you have a leak then that’s just a better excuse to upgrade to a much larger tank. You see how that works? Expect to see this in the European Union and the United Kingdom as the States won’t receive any of the Orca glue goodness. Just when the Euro is starting to drop too, darn.
