In my experience the aswer is no. I haven't done controlled experiements
and don't intend to, but I've had NO3 at 40ppm and PO4 at 5ppm and had no
algae at all. Those spikes came from a dramatic change in the tap water
that occured in late spring/early summer. THe only time I've had issues is
with those lower levels of nutrients. I think the reason for that is that
it is too easy for them to slip to near 0 ppm inhibiting plant growth.
