I have inherited a 1l bag of Tropica Plant Growth Substrate which I figured I would put to use in my 30cm cube (soon to be after nearly two year) Betta tank.
Planning on capping it with some fine gravel or sand but just wondered how much the substrate will end up mixing with the gravel and whether I need to put some sort of membrane in to stop that?
