Love this scape, I never considered the use of driftwood from the beach as I thought it would leach into the tank. I also live on the coast, 5 min walk from the beach, I have loads of bits of driftwood in my house, mostly unusual bits of root etc. I just use them as ornaments as the textures and shapes after long periods in the sea are amazing. How does one prepare them for the aquarium? Do you bake the, on low in the oven to kill bacteria and then soak for a long period in fresh water to get rid of the salt etc? Also, what yogurt did you use for the moss and what is the technique?
