Its what I get for not soaking it. I bought it at my LFS. It turned the tank water to a brownish color. The tank has been up for almost two weeks now. The driftwood also has white cloudy slime growing on it. I tried adding nutrafin waste control since I got it with my tank. I'll see if it helps in the morning. As far as tank water can I do a big water change tomorrow? Around 40%
