I'm not sure... I think the lights on the aquapod are a little stronger, but not much more. As of now I have stock lighting, but I did order metal halides today. You can also add an extra PC inside the hood of the biocube... I was going to do that, but I want to add an anemone and clams, so the metal halides would be best.
stock lighting is fine. You can add a good variety of corals. My corals grow well and always look really healthy.
