hello i will be getting a new tank, and would like it to be high tec (he says crossing his fingers) i dont really want to spend much money on the substrate as i need to buy co2 and new t5 tubes ( 2 39w t5 ho ) which will all be in a 100 litre tank. so i was thinking has any one had good results with Akadama or is there better stuff out there for the same money ?. and how do YOU use it ?. picutres would be great
