I brought back some pieces of wood from mexico 3 weeks ago, (seen here: http://www.aquariumadvice.com/download.php?id=15652
) and want to use them for aquariums. They were ID'd as cactus "skeleton" in another forum ( http://www.aquariumadvice.com/viewto...=499349#499349
) but I wanted to see if anyone here has had experience with this stuff. I'd really like to use it but I've been told it will decompose waaay too fast.
