if you end up getting the bulbs from the web site here's the same combo of spectrum as what i mentioned but in the ATI brand that they sell. Like i said take note that the names changed but the spectrum are almost identical.
1 of Aquablue special
this bulb is like a 12 k spectrum bulb.
4 of ATI blueplus
this bulb is like 20k to 22k spectrum bulb
and 1 KZ fiji purple
this bulb enhances pink, red, and oranges. not sure what the spectrum would be but i love this bulb on my tank.
This combo rocks and enhances blue, green, purple, red, and oranges in the color spectrum as welll as the fluorescence colors. All those colors will "pop" out at you and you will get lots of contrast between the colors. If you use the light bulbs that you posted earlier the colors will be washed out and little or no contrast. After you get the bulbs we'll talk about bulb order from fron to back in the fixture.
