Thank you Brad. I'm prepared for the cloudy water so I don't mind that. I'm only going to be using about a 1/4-1/2inch layer of the laterite on the very bottom with another inch of aquasoil on top of that & then about two inches of ungraded black gravel to cover it all. I will have some Riccia as well as java moss & anubius 'nana' attatched to bogwood so I will be using Flourish as well. Do you think that will give me too much nutrients & cause algae problems or should it be ok? The tank will be fairly heavily panted with a mix of fast & slower growing plants with co2 at around 20ppm. 156w T8 lighting, 18inch deep tank.
