It could be the picture or lighting, but the tissue looks "bleached" to me. Should be "purple" if healthy, even with the polyps retracted.

Where's it's location in the tank. Mine loves low light.

Thanks for the quick response, the tissue has always been a pinky white colour, never been purple. GSP has been growing like a weed!!! Just noticed this this morning. Rest of the coral seems healthy

Any idea why it might have suddenly decided to do this?

Thanks

sorry, very close to the sand bed, medium flow

How often do you do water changes? Could be lacking something.

 

[alex7miles]

25% once a week. Is it worth just keeping an eye on it?

Yes, of course. What lights are you using and how long are they on?

Do you have any other corals near by that could be touching it?

 

[alex7miles]

Not got the best light. Its cheap! Came with the tank as a set up. Have it on 8 hours a day. It is enough to grow stylophora though so dont think the GSP would have an issue. Have zoas, euphilyia and acans as well, nothing is remotely close to the GSP

Just found this photo from a couple weeks ago looks like quite a considerable chunck has gone

Okay, could be a water parameter issue.

What's your water parameters?

 

[alex7miles]

Sorry its taken me so long, was out of the house. Just finished an up to date water test

Nitrates are elevated but ive seen worse, due a water change btw

Temperature - 25°C
PH - 8.2
Ammonia - 0.0
Nitrite - 0.0
Nitrate - 21
Phosphate - 0.01
Salinity - 1.025
Alkalinity - 8.5
Calcium - 440
Magnesium - 1460

Its a 25% water change sorry, Not 25%

Nitrates seem pretty high. All
other numbers look pretty good.

Yeah, gonna do a 25% tomorrow, check the levels again and then potentially another water change on tuesday. Hopefully it helps

GSP can be finicky but also impossible to kill . Water change and I bet it bounces back
