I think a lot of us wish we knew.  I don't think there is any one factor
in sudden changes like this, but rather a sudden convergence of several
factors that produce conditions unfavorable for algae.  Light, dissolved
nutrient levels and competition are the things we can test and see.  We
can't see changes in dissolved organic chemicals or in the microscopic
ecology in the tank. I have to suspect that the last two are key to the
unexplained changes that sometimes happen in tanks.
