Ok I have had most of these Ricordea colonies for many years most of them for more then 6 or 7 years. I did add a few newer ons from a fellow reefer maybe 8 months ago and they have been growing well during that time. Then I noticied one of the new ones seem to be bleaching out a little, then shriveling up slowely over a period of time. Then is seemed to spread to another in that area, then to another on another rock and now it seems to be affecting all of my Ricordea. I have yuma, Florida, and St Thomas Rics and they are all in the same sad shape. They are all over the tank in all different lighting conditions from top to bottom. They have always done well and I have nevre ahd any issues with them.

I just did a water change and measured my parms:

Salinity 1.024
Ammonia 0
Nitrate 0
Nitrite 0
PO4 ~.01
MG 1180
CA 450
KA 11
PH 8.2


Now I have recently changed my lights from T5's to currently LED's w/ 2 T5's from 7 T5'S. With that being said this started to occur before the lights were changed it just seems to be spreading more now. SPS's, LPS, and other softies are fine for the most part duirng this time. I'm having a little issue w/ my SPS since the light chnage, but that is b/c I need more LED's which are on order. Certainly not related to the Ric issue. I really don't know what to do with these? Its very weird since I've had them for so long. Its not like I got a stressed sample from a store and it melted down these have been in the same tank forever. They have lived through tank moves, power outages, salinity issues basicaly everything over the years and now they are disapearing when all seems fine??? I haven't been fragging them so its probably not a bacterial infection? Can they catch the Ric equivialnt to the Flu??Any thoughts beyond the standard stuff would be appreciated.
