4 Gallon Nano Reef Lighting

Hi all,



I just recently setup a Nuvo Pico Tank for a nano reef. I am running the stock lighting but am not happy with the washed out colors of my corals. SO I'm looking for opinions to upgrade the lighting for better color from the corals.



Any opinons on upgraded lighting?



Also, it it unrealistic to think about lighting that can also support hard corals?
