In general do corals change color as the grow? If i buy a coral thats colors arn't very bright from the store will they become brighter as the coral grows or becomes more healthy in the tank?
also i saw ziggy953 post this as a reply in another thread and wanted to ask a question without jacking that persons thread.
"Well the short and long of it is this. Start setting some cash aside to either buy a new fixture or a diy kit of some kind. Even though you have your clam up high in the tank I don't think you are giving it enough light. I know that doesn't help you much. I have the same tank you do. I have dual 175w MH
(10Ks) 220w of VHO
Actinics and 108w of T5 blue actinics. (678watts total). I didn't have that to start off. I slowly added to my lighting. I actually started with a PC
fixture 260w I think. Eventually I got the MH
ballast and bulbs, then added the VHOs and just recently added the T5s. With your tank like mine they are deep and you are going to need some decent lighting to penetrate to the bottom. As Fiji said the bulb has to match the ballast. Trying to fire a bulb that doesn't match the ballast can damage both the bulb and ballast. If you would like to see some pics of my set up let me know. I have pics of the canopy I built to house the lights."
What is the difference between the VHO
actinics and the T5 blue actinics? Are they the same kind of light just comming from different kinds of bulbs?
