Hi all, I'm new to the forum but I have been in the hobby for a few years now. I recently built and set up my pride and joy, a 250 gallon fresh water community tank. It is established and has been running well for about 5 months. Recently I noticed a growth of someting (algae or fungus) growing rather rapidly on the piece of Malaysian driftwood that I have as part of the aquascaping and for the life of me I cannot figure out what it is. The driftwood was properly treated before it was placed in the tank (boiled and soaked for two weeks) to ensure no contaminates would be introduced. After noticing this growth, I removed the driftwood and proceeded to scrub it as best as possible and pressure washed it to remove any trace of the growth. Well after placing it back in the tank, two weeks later the growth is back and bigger than before. Has anyone experienced this problem, and if so, what can be done to get rid of it without harming my fish. I have included a photo in the gallery titled "Driftwood Growth" to give an idea of what I am fighting.
