Best wet reef safe rock glue

[anthonyc63]

Anyone have a recommended 'already wet' use reef-safe glue? About to do a large shipment of corals and want to redo the scape to open up more coves/arches. Currently the entire scape in my RS Reefer 170 simply stands on its own, rock over rock - using Walt Smith 2.1

I've seen some purple glue/putties and I've love to use that as the rock itself is dyed purple already.

What about rescaping in a tub of saltwater separate from the tank? I used the two-part purple stuff in a tank but it made my skimmer go nuts for a week.

Could also try some simple drilling with long bits and inserting carbon rods, if you can keep the drill out of the water. Or maybe a flexible drill extension.
