GSP- No polyps for a month

[MichaelReefer]

I've had GSP polyps vanish here and there, but never for this long. All of my SPS and LPS are doing amazing, just not my GSP? Any ideas?

Alk 9.0
CA 461
MG 1301
Salinity 1.026
78 Degrees.

Pic? Nitrate / phos? Something could be eating them or water quality issue / flow would be my guess. I did have GSP eating nudis before they exist lol

No pic, just randomly thought about it so checked my Apex for the other stuff. Normally they are sitting around .2 nitrate and .3 phos (tested last week, they were closed up). I have plenty of flow and haven't moved the powerheads in nearly six months but were fine before. One day they just didnt open up.

Nitrate is a little low- could be zeroing out during the day causing GSp to be unhappy? Not really sure probly something can be irritating it / eating it

Sometimes they will close up for weeks on end to attract the cleaning crew for cleaning duty. You can always try "dusting" them off and temporarily relocating somewhere else in the tank.

Never really had pests, only Bristle worms in the refugium. Montipora Digiata is growing like a weed, all my Acropora as well and Stylophora. Honestly, tank is doing better now than ever before, and super stable.

Bring salinity to 1.024-1.025.
Additionally they will do this when there is a layer of dust on them known as mulm. Simply take a turkey baster and give them G E N T L E Bursts of water and within hours they should perk up. Theyre open best in moderate light and water flow

I will try again, I took one of my Neros and blew them off last night, hoping it would help but nothing so far.

As others have stated, there can be many reasons. Though these things are hardy, when they get ticked they get ticked. When I first got my first frag back in the spring mine closed up for about a month. After trying a few things like adjusting placement and flow followed by a week of observation in between, I decided to give it a nice brushing with a soft pipe cleaner. Within a few days, and one by one the polyps opened up.

By the time I decided to upgrade tanks months later, it was starting to encrust the rock it was one really nicely. I had to cut it up quite viciously to move some of the rock and empty the tank. I put some of what I was able to peel off successfully in the new tank and that took about a week or two to open up. The parts of the mat that remained on the rock I put in the new sump I assumed was just going to die since I hadn't set up the refugium yet. Weeks later, I put in a refugium light and some chaeto. A few days after that I saw the GSP polyps opening on the sump rock, too. I still check on it every once in a while. It is growing and, aside from a nasty mat of algae that covered the GSP, the polyps remain out and open. I'm pretty sure the nasty mat of algae is actually the GSP mat that just looks different under the pink refugium light.

Once you give it a brushing, give it some time. It will open on its own.
