replace two of the stock 10000k bulbs with one gisseman blue and a pink/purple.
now the color is way better than before.
i did some research on the forum and tons of people recommend 3 blue + 1 white + 1 actinic + 1 purple/pink bulb..Great looking rock arch, new lights and Tank. What made you pick the two new light colors? I don't like the stock lights in my RSM and your pictures look more what I want.
Thanks J
