I'm new w/ SPS's but have had a tank for more then 6 years. I have a green slimer frag that isn't doing good. It initially grew and encrusted the plug but now the tips are looking whitish and it seems like red algae instantly grows on the tips. Looks like its working its way down the coral. The bottom is still bright green.
I have a blue milli that is bleached out as well but it isn't growing all of the red stuff like the green slimer. I have three sunset millis and a bonsi that are all doing fine. Good color, polyp extension and good growth.
5 new T5s. Just swaped the bulbs last week.

water params are good
CA is above 400
They just don't seem to be happy. I blow off the red stuff and it comes back instantly. No cyano or red stuff on anything else really.
Any thoughts would be appreciated.
