Bulb placement suggestions.

[Carrera75]

I have a 24" Aquactnics that I'll be using on a 34 gallon Solana. This fixture holds 5 bulbs but I purchased 7 bulbs to have more options to play around and see what combo works best. The big question is in what order should I place these bulbs.

When suggestion a bulb combo keep in mind that the fixture has 2 switches.
Switch #1 controls bulbs 1, 3, and 5.
Switch #2 controls bulbs 2 and 4.

Here are the bulbs that I bought..........

3 ATI Blue Plus
1 ATI Purple Plus
2 ATI AquaBlue
1 GE 6500K
