I am moving my nano from a 20 l to a 29 so I cankeep the hood and stand. You could do t-5's or VHO easily. I had 4 x 75 watt VHO over my 20 long for a bit till the heat broke the lamp rack. Since it's such a shallow tank t5s would work well for softies, lps and probably montipora too. The color is great too - only problem is bulbs are expensive.
