于 2004-08-27 14:27 Light and current are the most important factors. YOu need at least 150W MH to have grow. For better color, 250W and up is beter. I am using 2 x 150W 10000K bulk and have to place the 角珊瑚 at the top of the tank. to have growth. The color is so so depends on which kind of 角珊瑚. I wish I have 250W light instead.
