Can anyone tell me what this white stuff growing on my driftwood is? I am in the middle of my fishless cycle and the light in my tank is never on, I turned it on tonight just to have s look and noticed his white fuzzy stuff growing in the cracks of my driftwood. How concerned should I be? And can I let it be until it's time to put fish in there? Thanks in advance for your help.
