Maybe this can also be one of a good way of reducing the needs of importing live rocks from oversea as well ? Indirectly reducing carbon emission produce during the process of importing all these HEAVY ROCKS via all the air/ Land transport before reaching our shore ? Since Live rocks play a major role in the success of our hobby as well as the overall biological stability in the sea, it maybe a good alternative if we are able to have Good Quality Live rocks cultured ourselves. However, prices should be attractive / affordable in order to promote such activities.
I still remember a few year back where AVA started to control the importing of Live rocks and prices was at all time high ...
