I have been fighting this stuff, whatever it is for months or more. I have tried all kinds of things but I cannot get rid of it. I clean it off my fake plants every week, and rub it off my live plants as well.
I have reduced the temp to 72F, reduced the light time to about 10 hours, change the water every week. I use Algae Block which works great on the green algae but allows this stuff to thrive.
I have a UV sterilizer. I have tried PhosGuard Phosphate & Silicate Remover.
I moved the heater over near the OTC filter and the black stuff grows better over there now.
