So the new bulbs are in the same fixtures?

yes.

And you don't say how long you had the old bulbs.

approx. 3 months, they were new.

Maybe it was just a
coincidence that your algae problem started with the new bulbs? Do you know
your nitrate levels?

generally from 4-8ppm.

And you
may need to add at least an iron supplement, such as TetraFlorapride.

won't that affect the ph?

you talked about trying two 10k bulbs. right now i have one 6500k and
one 50/50...i'm a little hesitant about going out and buying 2 new
bulbs. maybe i'll just bite the bullet.
