I have no personal experience with this stuff Paul. But from everything that you can read about this stuff its too bad you can't get it. Pound for pound, it appears that nothing else even comes close for value. I know that someone is gonna want to argue that point, but one good look over at PlantedTank where you have a whole lot of people that have used it - and other stuff to compare it with - you can see that it is great stuff for the money.
