I would love to be able to dose Excel or H2O2, but that would destroy everything. It also doesn't solve the root problem anyway (whatever that is). I'll try a blackout on a sample piece as suggested, but have little hope for that. I didn't know that worked on Marimo balls, so it's worth a try.
It could be just a different phase of the same algae, but I would think this would have happened a long time ago if it were prone transforming.
I try to remove the bad stuff manually, but I think that makes the problem worse. Every time I pull some out, little pieces break off and are dispersed around the tank. That's probably why it's covering almost everything now.
I'm also attempting a mass exodus of the trumpet snails in this tank. They could be a problem, I suppose. I'm sure there are tons of them hiding in the substrate.
As for the lighting, I'm not sure if I should increase or decrease the photoperiod, or if I should raise or lower the lights. Lessening the light levels would probably just slow the growth of all algae in the tank, but probably wouldn't do much harm to the unwanted algae. The good algae seemed to like light. The lamps are getting old, so maybe its not getting enough light? If that's the case, it might be a good idea to increase light levels.
It's a shame this is happening. I hope i can fix it. If I manage to get it back in line, and grow a complete, lush algae carpet, I expect to win some kind of master algae grower award. But don't start planning it for me yet, guys. I'm pretty sure it's doomed. We'll see.
