my purple pavona coral that is about 1.5 months old for me now. has slowly made a transition to light green. it dosent look to good. i think. it is about 8 inchs from my t5 lighting.

6750k
20000k white
actinic two of them.
those are my bulbs kelvin ratings.

i think i need to get a better selection. does any one have 4 t5s on a tank similar to a 55long aga. whats bulbs are you running. and if ne 1 has ne info it would be much apprectated. thxs

Is it beginning to bleach ? Is there any polyp retraction ? The color change could be because of the light intensity, what are your parameters cal/alk/mag ? Do you have any other SPS and if so how are they doing ?
