sick sps

[wav0718]

Any ideas/experience with sps skin looking thin? All other corals look great but these two just don't look right to me. ALK 10, Cal 500, Salinity 1.026, Temp 78, Mag 1450. I run phosban, carbon, cal rx. SWC protein skimmer, vortech and tunze for flow and an ati 6 bulb sunpower t5 fixture.

Here are some pics

too much flow? direct flow to the coral can rip the fleshy portions off of the coral. also too much carbon has caused "SIMILAR" appearances in my tank, but im leading more towards the flow.

I'm not sure about the first coral, but the second one almost looks like nudibranchs have munched on it.


Were they dipped recently? I ripped the flesh off a frag when dipping it a little too enthusiastically. I was watching an aefw lay eggs while my water was mixing for the dip.
