T5 bulb spectrum Question

  1. billyboy2 Member Member

    hi i just purchased a HO T5 lighting system. It's got 4 bulbs 2 are 10000K and 2 are 6700K. Are these the best setup with T5 lighting or are these bulbs not in the proper spectrum for reef tank??

    They should be two bulbs @ 10000k and two actinics aka blue lights those will be ether 420 or 460 actinics. 6700k I belive are more for freshwater plants.:;hf

    The 6700K are indeed ideal for FW planted tanks. For SW get two T5HO actinic lamps and just replace the 6700K ones.
