If I've learned anything in the past five months, it is that algae is very resilient and adapts to live in pretty much any environmental condition.
I have a piece of driftwood that became engulfed by BBA and BGA. I pulled it out of the tank and set it in the garage for several weeks. A few days ago I decided to put it in another tank. The BBA was easy to see, as it dried to a shiny black sheen. I took a wire brush and scraped this off. The wood looked normal after this, no green or black coloring. However, yesterday I put a light on the tank and noticed that the wood had quite a bit of green, I assume where the BGA was. It's not blue green (like live BGA), but more of a fluorescent green color. Could the algae still be alive and cause another outbreak in the new tank? Ore is it just residual dead algae? The wood dried out for 4-6 week, and showed no signs of moisture.
