I looked through the older posts for an answer but couldn't find anything so I thought I'd ask. Yesterday I put some very dry drift wood in my vacuum chamber in hopes of stabilizing it. What I noticed was that at first the CJ bubbled up to beat the band. But within about 10 minutes the bubble blast had stopped and all that was happening were some very small bubbles. Within about 2-3 hours, no bubbles. Is this normal for drift wood? To bubble up and then quit so soon. After removing the vacuum the wood started absorbing a lot of the CJ to the point I had to put more CJ into the tank. Any thoughts or ideas are appreciated.
