Looks really great! What bulb combo are you using? When my tank was setup I went back and forth between UVL/ATI and geismann. I really like geismann bulbs for other things but ended up loving the more popping blue of ati/uvl. For some reason to my eyes the t5s can look washed out but it takes some playing with it to get it just right. I think the trick is to have 03, 03, a purple (460nm?) and a white or the super actinic plus which is like .. inbetween blue and white like a 14k MH equivalent.
That tank will be really nice when its full and mature!
