My green spot algae problem was caused by to high of light, in comparison to my co2 and fert levels. I was able to slow it down by running phosphates at 4 - 5 ppm, but it didn't go away until I raised my single T5HO bulb. If you have a certain par, you need a certain co2 level and a certain fert level. If your light is very high, your co2 and fert levels need to be very high. If you are running all 3 of those bulbs on that Catalina fixture, assuming it not raised above the aquarium, you are in the "to high" light range, which means the only way to get enough co2 in the tank would probably kill the fish. I would definitely only run 2 of those bulbs at the most, and make sure your co2 is high. I can't really coment on your fert levels, since you did not post them.
