Review: Filter Media - Great and original product, would recommend using original product.
Review: Why packs of 3? - I have absolutely no idea, why these come in packs of 3? I have the fx6, so I require 6, to fill the trays. The fx4 requires 4? This is not too bad for me, as I buy to packs and sorted, the fx4 owners must be fuming? Why not pack in two's makes much more sense? These are relatively expensive for what they are as well.
