I want to use Dragon Stone for the hardscape and the substrate i will be using is Florabase, i plan on banking up on back left and back right (anyone have any tips on how to acheive the height without it falling?).
There was a post on here not so long ago in which a guy used nets full of the brown/red, dry, light, bally things that you see in plant pots in shopping centres and airports etc. to keep parts of his hardscape up. And it seemed to work brilliantly, cheaper than buying more substrate!
He also mentioned that the inside of them is porous - therefore it would give him more filtration capacity.
Hope this helps
