于 2005-03-09 13:28 i don't even think their is 6000K...do you mean 5500K or 6500K?????? If you are planning to use 6000K MH...... If you really want the light and keep it cheap....I think you should go with 2 x 110W VHO + 2 x 96W PC or 6 to 8 x T5 HO I think that better than using 2 x 6000K MH + just remember you want high level at 400-480nm( good for zooxanthellae ) many coral, anemone and mollusks need zooxanthellae as food.
