Check out my journal and the journals of other people with this tank. Lots of discussion on fixtures.
Finnex fixtures are great but they will provide a ton of lighting. You will have to raise the fixture extremely high above the tank and will still have to use pressurized CO2 and EI fertilizer dosing.
