Of all the advances in the marine aquarium interest, which do you consider number one in importance? Improved lighting, new and enhanced filtration methods? Captive breeding and rearing of livestock? Treatment, capture, shipping protocols?
For my part, having "lived" the hobby and industry thirty some years, it’s actually none of these. Though great strides have been made in keeping saltwater life, much of the credit should go to the popularization of Live Rock (LR).
