Am currently using four Geisemann Midday T5ho bulbs and it is getting close to the time to replace them. Would like to try one of the Aquaflora bulbs but am having a hard time finding them. I came across the Korallen Zucht Fiji Purple bulbs on Reefgeek's website. They state they peak in the red and blue spectrum, which sounds good, but I can't find a spectral distribution graph for them. They are designed for reef tanks but am wondering if anyone has tried them over a planted tank.
