What type of mold/Algue is this?

[Ravelle]

Aquarium that's been running for a few weeks along with this new driftwood in it started having this white moldy stuff on it,  I've had bio film before which resided quickly but this won't go away,   I've already soaked it with hot water for a few hours before use,   took it out once before and gave it another rinse and put it back it but it came back.

Did a water change and it otherwise clear as day.

My narrite snails pretty much leave it alone as well.

It’s a bacterial bloom from the wood. Perfectly normal and harmless. It’s digesting the edible bits on the wood surface. When that’s gone it will disappear. Fish will also eat it. If you can’t stand it, gravel vac it off. But it will come back until it finishes the process.

When I put my mopani wood in the growth got to 2 inches thick in spots.

Ah that's good to hear,   it doesn't bother me that much but kinda puzzled  because of the thickness of it and the other wood types had no issue,   I'll let it do it's thing then.   🙂

Thanks!
