Got news of this
"It has just came down that August 4th, 2008 will be the last time Tonga is able to export Tonga Live Rock.
Currently the suppliers in Tonga are trying to negotiate a 2-year phase. We have no idea if the Tongan suppliers will be able to make any advances in negotiating this deal but it is for certain, any way you look at it Tonga Live Rock will be banned in the near future.
For now, August 4th is the ban date and if the 2-year phase out is granted we will let you know.
In the meantime you have 5-weeks to get any and all Tonga Live Rock you need from us.
it appears this will be the last month you'll ever see Tonga Rock of any kind available again such as Tonga Branch, Deep Purple, Kaelini, Deep Water, and many others from the tonga islands seen here... "
