I seem to have bought jati driftn wood. It Sinks and it is not making the water in the bucket its in yellow . it cost me 5 euro and is around 1.5 feet long. It was heavy before I wet it but it seemed dry . it was bagged like from a factory. Some of the other pieces were like this too but others were light . can I add it after I pour some boiling water over it ? Is it aquarium ready ?
