Running two bulbs without CO2 will give you algae. I have a three bulb setup from Catalina and run only two bulbs and, I have to really blast the CO2 and fertilize daily. Ask Jim to price you that fixture with two switches, one for each bulb. And ask him to substitute 6500 K bulbs for the 10000 K and actinitic. He will accomodate you. Explain its for a low tech planted tank, he'll know what you are talking about.
