Hey everyone happy new year!! Ive been looking to replace the bulb for my 250watt hqi, the current one is 20k and has about 14 months of use on it. I think it is too blue and would like to switch to something like 12 or 14k to get more of a natural look from the corals.. Could this have a negative affect on the corals? I would think not because it would be like buying frags from someone with different lighting but i would imagine there would be some precautions i should take, especially with the "burning in" phase.. this will be the first time changing bulbs as ive only had the tank about 10 months so any help would be much appreciated.. so would suggestions on temp and the best bulb for the buck. here are some shots of my additions from the swap..
