It's AS I, I did have a really really nice branch in there. I believe it was Oak that I had found. I de-barked it myself and baked it. I soaked it for 72 hours outside and put it in the tank but it still floated, so it sat in the tank from 5-02 until yesterday when I planted the hairgrass. It still floats and it was covered in white whispy slime...? I'm not really sure what the deal with that was so I took it out. I'd love to have it back in but dealing with it floating sucks, anytime I change water or have to re-plant a stem it floats to the top and disturbs the AS causing more cloudiness. Not to mention the rediculous amount of tannins it was leaching into the water, it was like staring and mud soup.
