How much darkness kills off hair algae?
I've got a 300g inwall display that is OVER RUN with hair algae. I've blacked out the front with a single sheet of parchment (except for a small corner of macro I like) and the back side has curtains pulled over it. It's been closed up for a week with only a slight noticable improvement. How black (dark) does it have to be?
Thanks,
L.R.
