Low/Medium light recommendations for 75G
I'm looking for lighting recommendations for a 75G tank (48" by 18" by 21" high). Based on my calculations (using the various graphs on this forum) it seems like a fixture with 2 T5NO bulbs with a very good reflector would suffice or possibly a single T5HO bulb fixture with a good reflector. Unfortunately both of these don't seem to exist. So I'm wondering what people would recommend for lighting this tank in order to achieve low to medium light (in order to avoid CO2 and minimize algae problems).
