Beautiful tank vitz! I really like how you have the tiers. I've just started using the excel in my 46G planted tank. Is it really what it's all cracked up to be, as a good substitute for CO2? I really don't want to mess around with CO2 as I am only running about 2wpg, and think pumping CO2 in would be a waste.
