So I recently just picked up some wild driftwood from my local lake a couple weeks ago. I looked online and most forums said to soak and boil it, so I soaked it for two days, and then boiled it for ~30 min. But weeks later, I see this white color on the wood (See image), I looked online, and have seen websites about a white-ish fungus but not anything about this streak of white. I have since removed that price of driftwood from the aquarium. But if someone could tell me if this is safe or not, or why this is happening, please tell me! Thanks!
