I just started up a diy co2 system in my ten gallon tank that I've been having for a year or so, its only been a week since I had the co2 going and I notice this today, im sure its some type of algea but I cant seem to find anything online that looks much like it so if anyone can tell what this is so I can find a solution I would greatly appreciate it! It seems like this black kinda of film that's growing on the top of my driftwood cave

duuno, but I would scrub it off
good luck...

 

[bradleyjames77]

Weird right? Mold comes to mind, il scrub it off and hope it doesnt come back, thanks for the input guys

Definitely looks like a bacterial film. Why not leave it? Biodiversity is always fun.

I had some bryophytes show up on some driftwood, way cool and would reform every month and after 2 years just went away. I enjoyed them while I could. Not sure what you have though, good chance it will go away once everything settles and the tank finishes cycling.
