GSP problems?

[silverdak]

Lately my GSP have seemed to be shrinking and dying off, last water test came out fine and only nitrates were 5 which was fixed after a water change. tank temp is a steady 76 degrees. calcium is about 550-600 (better than the 700 is was!)
when I first put them in a while back they started growing and spreading like wildfire!, nothing has changed since they were added, lighting is the same, flow is the same salinity was a little high recently but now it lower... I just got the lights on a better schedule, and all of my other corals look great, just a little worried about these guys.
Thanks!

how r the other corals doing? make sure there isnt any detritus on its mat.

all the other corals look amazing, they open up and look great. I blew it off today and yesterday with a turkey baster, didn't seem to do much...

anyone?? could it be the hair algae taking it over or something? I LOVE my GSP... but they arent looking too good. they cover a good part of my top rock, but have been slowly disappearing, and its making me sad.

Calcium is high (you want it at 400-450)....have you tested your Alk?

Just a thought, awhile back my GSP's closed up tighter than a bull's

at fly time.
I found these guys all over them:
Attachment 217196
They were some form of nudibranch/hitch-hiker I picked up along the way.
They seemed to colonize on my GSP only!
After removal everything returned to normal.
Not saying this is your problem, but it did happen to mine.
More food for thought.

hmmm ya I was thinking it could be something eating away at them but physically I dont see anything..... which is what is puzzling me.... I will try to snap a few pictures of them up close... lets hope macro works lol

SilverDak, once again, this might not be your problem, but these guys are very small and look just like a GSP when it closes up at night.
I didn't even notice them till I got out my magnifying glass and saw them move!
I pulled off about 30 of them.They didn't kill my GSP but they did keep them from opening until they were removed.

Your calcium seems outrageously high. Might be getting too much of a good thing there. Whats your other parameters?
