Just some guy, you know?
If you are looking for opinions, one of my favorite tanks would fit that light perfectly. The standard 120, it's 2 foot deep, 2 feet high, and 4 feet long.Like I said, I haven't chosen a tank yet, wide open to opinions.....but am picturing having 1 of my 4' (8) bulb t5's supporting it.
Am leaning towards a shallower tank....I like the 24" depth of this one. So keeping PAR above 250 will be a breeze.
