Jake and I discuss this all the time. Enough to drive everyone else crazy at dinner each month. I could go on for hours on each item, but will probably try to stay out of this topic. Adam ------------- Come to a meeting, they�re fun! |

Don't corals change color with age. I read a book at
barns & noble and it showed pics of corals and how much they can change with age and lighting. ------------- Josh Zorn 45G reef lots of tropical plants Cell it 910 3924 |

IMO, lighting is the greatest factor. ------------- www.captivereefing.com |

I mostly agree with Adam. I think the two biggest factors are light intensity and spectrum. ------------- Jake Pehrson Murray http://coralplanet.com" rel="nofollow - coralplanet.com http://utahbeeranch.com" rel="nofollow - :) |

I think that in our tanks (in my limited experience)
that
lighting intensity and spectrum have the most impact on color of my
SPS. From everything that i have read 6500K and 10K will give better
growth and 14K and 20K will give better color.
One thing that i have not done is to take a coral
out of my 20K tank and put it under the 14Ks to see if it looses color.
I doubt i will get the chance ... I think i am going to switch the 14K
for a 20K when this bulbs is due for a change. I am VERY happy with the BLV 20K bulb. I am
currently running 3 light configurations and have kept the same frag(s)
in all
three. I can post some really interesting comparison pics of a frag
that i got from
shaneH, if you'd like. The pics of this coral are under
14K(Hamilton)/T5s, 250w 20Ks(BLV), 150w
20Ks(Ushio), and a pic of when i very first got the frag from
shaneHs tank (10K/VHO). The difference in color of this coral is simply
amazing under the 20K 250s. I think i may have pointed this out to Jason, when he was over recently... |

First off, I don't think there is a definative answer to this question. It can vary between different corals. if you give coral A too much light it will develop more of pigment Z to act as a sun screen. Pigment Z might be a desired color or it might not. If you give that same coral A too little light it might develop more of pigment Y to better harvest what little light is available. Pigment Y might be very different then pigment Z... it might even be more desirable. It is the intensity of a particular quality of light that is important as near as I can tell. And water quality does play a role. I don't think SPS will really color up if they're in nutrient rich waters. ------------- Jon https://www.youtube.com/channel/UC6y_EzjI_ljbIwf2n5uNzTw" rel="nofollow - What I've been doing... |

| I have also read a few articles that say that alkalinity plays a large role in the color of corals |

I took this question to mean what makes a coral red or green or some other color. Lighting can make for different shade and even different colors, but I have a frog spawn in my tank with 2 heads. Each head is a different color. For all intents and purposes this coral gets the same light. With this coral being pretty much the same thing, (they share a skeleton,) why is one green tipped and the other pink tipped?
