Substrate Membrane

[Gav_B_UK]

Does anyone know where I can purchase (online) the membrane to put between a gravel base and a sand upper in my substrate?? I've seen it somewhere, but can't remember where....

Thanks in advance...

cant say ive ever heard of these are them semi-permeable?

Someone on here mentioned it when they did a posting about their sand and pond soil substrate. I don't know much more than that....

Wouldnt it just be a plastic sheet of some type that goes ontop to prevent the two mixing? Or is there an actual product designed for this in mind?

Apparently its a product designed for it....its sounds as if you can plant through it (obviously by creating holes)...and it also sound permiabable from what I was reading...the annoying thing is that I did find it in an online shop...but I didnt save the link!
