Subject: Single-celled Algea?

I recently (6 weeks ago) set up  my first planted tank. All the plants
started to take root and grow nicely. Then over a period of a week in the 3rd
week I started to get green single-celled algae. There is a little hair and
bearded algae attached to things, but the water is clouded with this
single-celled green algae. 

I've read on this list that I may have a trace element shortage. Water
changes do not help (MA. water is soft, KH <1, and alkaline, pH >7.6). I
added 5 grams of Epsom salt + Kent fertilizer. I am not sure if that helped.
The tank did begin to clear, but then clouded up again. I added an additional
5 grams of Epsom salt when it began to cloud, along with a water change and
fertilizer to no avail. The plants are growing well, but some are slowing,
probably because the light is being cut of by the algae.

My dreams of a beautifully lush planted tank have been dashed. Now I have a
big tub of pea soup. Can anyone give me some suggestions on what to try?
