ok i had a yellow finger leather for awhile, and it did pretty well under my floresnts, but now i put it under my pc lighting and its turning brown and dieing! you think to much light for him?

I also had the exact same problem with my montipora. My brother had his monti on florescent light, and he gave me a frag. i was fine under my PC lighting for about a week, and then it died on me. the water quality was fine, so i am thinking that it is the PC lighting that did it.

hmmm weird you would think the pc lighting would help with being brighter

Acclimatization speed perhaps, or complete lack thereof?

If it was acclimation speed for me, then why did it last a week doing perfectly fine, and then all of a sudden dying? Im pretty sure i acclimated it over about a 3hour period.

I'm sure Teevee is talking about Light acclimation. Corals need days or weeks of acclimation to large changes in lighting

and how would i do that? i dont have florescent. i only have pc

Also I'm not sure you can use physical appearance as an accurate indicator of overall coral health. Then again perhaps you can, but it's something to keep in mind.

ok i never thought of that (dork i am)
