I've got a 22" deep 33gal hexagon tank, currently using a Coralife Aqualight T5 fixture (28 watts total). I want to upgrade, or combine if possible, a 48 watt T5 HO fixture or a 65 watt PC fixture. Question is, which is better for penetrating the depths of my tank? I plan on keeping macroalgae and perhaps some softies if possible, but these two types of fixtures are all I can afford right now. Ideas and advice?
