yea, thats the stuff, i didnt realise they'd been doing that for some time, its bad really imoI ordered the same stuff as you for my marines and it came in a funny bag that was made of out some kind of polystyrene, instead of that advertised, How many kilo's do you reckon I will need for my Rio? should I be aiming for about 2 inches?
I have used 3x4kg bags for my 125litre tank, and i would go for another one, you will always gain a little bit from where the rocks are situated, as these will need to go directly on the bottom of the tank.
