Re: Dark period and thread algae

It was an infestation of Oedogonium, a particularly nasty hair algae, that
finally prompted me to develop the 5% liquid bleach treatment, which got
rid of it.  Before that, I tried putting a gallon jar with Oedogonium in
total darkness for six months.  At the end of that period, the algae was
still alive, and it resumed growing as soon as it was returned to light.
