SPS and Zoas are Middle height, middle of tank.

Lighting question is:
For 'Sunrise/Sunset' I'm running the PurplePlus and BluePlus. 10 Hr duration
For 'Daylight' I'm also running the BluePlus and AquablueSpecial. 8.5 Hr duration

Sunrise/set looks odd with the purple bulb, and I miss the fluorescence of blue LEDs on my little Sunpod fixture.

Should I swap the purple for something actinicky (â„¢) or run both Blue+ instead?

Thanks for the help,
Blake
