hair/thread algae causes:
everything above quoted from... theplantedtank.co.uk/algae.htm
with more light you need;
to survive and thrive plants need;
the reason they're called micro and macro is because you need very little micros and a good handful of macros. macro = lots... micro = teeny bit... but the bottle has things backwards which is perfect for an overfed, over stocked, under lit tank... since you'll get nitrates and phosphates from food... but not enough for "high light".
THE BOTTOM LINE: plants need food. ferts are food. all the ferts create a well rounded diet and healthy plants. to never have algae what you need is healthy plants. plants thrive - algae dies. take away their food... plants die faster... algae gets worse.
hopefully my cliffs notes help clear things up for you.
