Hello and thanks for reading this, so in my aquarium I just established a new piece of driftwood and just did a big water change to my aquarium because I redid the landscaping and the day I put the driftwood in the tank It immediately started growing white fluffy stuff and I don’t know if it’s dangerous to my fish or not. Please let me know what you think (I have two otocinclus and a beta)
