laterite in Aust


I was just talking to my aquarium guy - he sells his own range of laterite,
dinosaur dung (balls) and dinosaur pee (liquid fertilizer).  But he has a
couple of Dupla packs in stock
at $25 each  - laterite that you place in the tank  with gravel (1:3)
laterite balls & tabs    suitable for a 200 litre tank.  He thought you
should be able to buy Dupla from anywhere.  Yell out if you want to know
more and I will chase up some distributors  for you.
