Based on my problems with the 260w Coralife fixture in my other thread, I am thinking of switching over to the 520w Orbit Extreme. Now, my tank is 72" long, but I must go with a 48" hood because of my canopy. So, the sides of the tank are always going to be darker - low light plants should do fine. I was planning on 2wpg with the 260w fixture, low light/easy plants, and no pressurized Co2 (or at least not right away). But now that I have an oportunity to change lights, I'm thinking of the Orbit Extreme with 520w which would put me at 4wpg - pressurized Co2 and high maintenance plant growth. But here's my thought - I won't use one bank for now....just 260w at 2wpg for low light/easy plants and Flourish Excell. See how my green thumb developes, see how I like it, and if I want to try higher light/more difficult plants with pressurized Co2, I have it - I can just turn on the second 260w bank for 520w and 4wpg. Any thoughts?
