Mercury/CF Lamps – 07/14/08
Hi Bob,
Am wondering how many aquarists are aware of the higher mercury content of Compact Fluorescent and T5 lamps.
<Doubtful many>
One T5 lamp contains 3mg of mercury and Compact Fluorescents even more. As you know, mercury is a potent neurotoxin and handling these lamps should be done with care to avoid breakage which leads to mercury contamination of the area. There are some states that have made it illegal to dispose of these lamps in normal trash pickup...they must be recycled.
Have a nice day, James (Salty)

T5 HO Bulb Selection 6/5/08
Hey guys!
<Justin>
I so glad this website is around to answer all my questions. I've been trying to look for the answer to this but am still in question.
<OK>
I just bought a 6 x 39W Catalina Aquarium Solar T5HO light fixture. It came with 3-10000 K and 3-6500 K bulbs. The light in the tank looks very yellow and was wondering what bulbs I should use (brand and temperature) I should use for the best coral growth?
<Any common aquarium brand bulb will work fine. If it is growth you are looking for, what you have is great. If you want to blue the look a bit, swapping out two of the 6500K bulbs for actinics will drastically change the look.>
I currently have just some softies and LPS corals, but would like to upgrade to SPS very soon. I am looking for more of a blue hue but it can still be fairly white. Any suggestions would be greatly appreciated.
<The above will work, with the SPS placed closer to the top/light.>
Thanks.
Justin
