Yes I will be doing 5 lb pressurized set up, I want high light for sure, from hoppys thread this is what I think it says. 2 t5ho bulbs are high light on a 20 inch deep tank, since my 29 is 16" high, and I will most likely use the mounting legs which are roughly 4" so I'd be at about 20" so that means with a 2x24 t5ho I would have high light? I'm looking at ancurrent satellite 2x24 at big ALS that has individual reflectors. It's not as many watts as the coralife 2x31 but I don't think the coralife has great reflectors, so the current usa would be better? Thoughts?
