This is my 24x18x18 terrarium. I plan to have a small amount of water flow across the back wall. I now have the walls covered with cocofibers, BUT what would be the best thing to line the streams wall and floor with?
I would use silicon or drylock. I used Drylock with the water area atop my waterfall and works great. The only downfall to drylock is it looks bad if you don't add color to it. Silicone lining with sand or pebbles would do the same thing and probably look a lot better. (The drylock portion of my water feature is hidden so I never see the bad coloring)
