Is 3 liters of substrate enough for a 12x12 tank bottom?
I have an eheim aquastyle 9, would a three liter bag of amazonia and a small bag of power sand be enough to get the approximately 12x12 bottom of this tank covered sufficiently? I plan on using some rocks but lets say if I chose not to: would those two products help to cover the bottom of the tank? Can anyone help me get a good idea how big an actual bag of 3 liter amazonia is? lol I just need to know if I should opt in for the 9 liter bag or not.
