I have questions about driftwood. What are the advantages/disadvantages to it? I found several really nice pieces yesterday, and want some in my tanks. But before I add them I want to make sure it does not cause problems. Also to sterilize them can I just pour boiling water over it. They are too large to fit in a pot on the stove. Does driftwood change the water parameters? I have one really awesome piece that I want to drill a hole in for a cave. I think my cories would really enjoy that. Is there anything to look out for that is a bad choice? I am assuming you do not want any soft crumbly wood. Thank you for your help. Sherry
