Not exactly sure if this is the most suitable place for this topic, so sorry and Im not sure where it is supposed to go.
...Anyway, I was hoping you guys could help me with this green plague that is creeping across my tank!
-The algae is very hard and not stringy and cannot be removed with a normal scraper.
-Applied force with a credit card can remove parts of it.
I was wondering if any of you guys/ girls had encountered it and how you combat it. And identify its name.
About the blur, phone cameras are all I have and they are not too good at close ups.
Thanks all for reading :-)
