Help Corals don't look good. Having trouble with pictures

[buffalobill]

I'm not to sure whats going on with my corals. They seem to have a white ring around the center of them. Not sure if the light is bothering them?Whether to much light or too little. I have 260 watt power compact in a 90gallon. Both corals are about 1/2 way up. Should I put them lower. My leather and all my mushrooms seem to be fine. My nitrates were 40 last time I checked and just did a water change so they should have gone down. Would old bulbs cause this?Any advice would be appreciated I'm going to try to attach pictures bare with me first time. Reply if you cant' open them Ok having trouble with pictures they say their to big any suggestions on making them smaller.

You can dowload a program like infraview to resize.

My guess is that they are not getting enough light with a 260 watt PC on such a deep tank. That is very little light with that depth.


EDIT: Here it is really easy to use after download. http://www.irfanview.com/

What types of corals are looking bad? Can you post any parameters? Temp, alkalinity, calcium, salinity?

Thanks for all the help. I went down to skiptons with my camera and got some help from Steve (always helpful). One of the corals looked to be normal while the other was possible bothered by light. This site is very helpful thanks again.
