I use 10,000k bulbs in my planted awuarium. I don't see any hint of blue at all. I think that 10,000k are perfict for plants, and the collours they give off look very natural. I don't know what people mean when they say that 10,000k give off too much blue light because I don't see any blue at all with my lights. Using lights for a saltwater aquarium works perfictly fine. I use the corallife compact flourecent light. I bought all the light secon hand from my neighbour that used them on his reef tank. He tore down his old reef tank so he could purchase a bigger tank, and he sold me all his lights for a great deal. I got about 340$ worth of lights for about 150$. They work great for growing plants
