Hi guys,
Just a quick one, I am going to rescape my Rio and I am considering a fertile substrate for a change rather than gravel like before, however I need some height and rather than buying loads of fertile expensive substrate I was planning on leaving the gravel underneath, but I don't want the new soil to mix with the gravel.
Whats the best thing to use to prevent the two mixing and where can I purchase it?
Many thanks
Paulo
