Another snake oil??

In fact, in 1997 the hobby was in a state of panic as a large number of stony corals were being imported with a fatal coral condition known as RTN (Rapid Tissue Necrosis) and Lugol's Solution was the recommended treatment until Warner Marine Research developed ReefPure Coral Dip and Conditioner which has become the current state of the art coral import and export conditioner..."
