Seachem matrix and ehfisubstrat are sold by the liter, so it's easy to tell how much I would need. I'm thinking of going with hagen biomax for the cost to surface are ratio, but unfortunately it's sold by weight so I have no idea what that amounts to.
Any idea what the approximate volume of a 500g box of biomax is? How much would I need to fill an 8"X8"X2" basket?
