Trachy Staying Closed

[Instigate]

I've had this trachy for about 2 months. It had quickly settled in and was fully expanding durring the day and retracting at night. The tank has been up for about 7 months and I only have about 15 or so very small frags except for the trachy. So I was thinking water changes would be enough to keep parameters up for some time. But I was testing to watch for a drop.

So, I didn't realize that the cheapo atc refractometers need to be calibrated every single time and my salinity had drifted as a result. Not knowing this I saw the alk/cal/mag drop and thought it was from my corals using them up. Now I realize it was likely from the salinity drop or at least partially from it. I raised my parameters with two part and am using kalk in the ato to keep them stable. Then I realized my mistake. So I've been checking the big 3 daily and raising my salinity slowly over the past few days and things are about in line. My SG is at 1.024 going to get it back up to 1.025 in the next couple days.

SG - 1.024
Alk - 9
Cal - 420
Mag - 1350
pH - 8.4

At their lowest it was:
SG - 1.022
Alk - 7
Cal - 340
Mag - 1200
pH - 8.2

Anyways, I'm sure the trachy not opening is due to the parameter swings. So I wasn't too worried about it. Figuring it will go back to normal eventually once things settle down and it has adjusted. But it's been like 4 days of it not opening. Yesterday I fed the other corals and the trachy wouldn't eat so the food I put on it was just blown away when the flow came back on.

I'm wondering when I should start to worry and if I should do anything at any point if it continues going south. Everything else in the tank has been totally normal.

Before the swings, it was inflating a bit more than this photo:

Right now:

I can see that it is inflating a small amount so I think I need to just wait and let things settle and it will be fine. But I don't have much experience so I though I should check in.

Also, my nutrients have been stable the whole time.

Phosphate - 0.1
Nitrate - 1

I would like to raise the nitrates to about 5-10 and lower the phosphate to .3-.8 but not too concerned with it atm.

I usually feed at night, but I'd just check on it and see if it can feed. Some people never feed them, so I wouldn't worry if it's a week or two. But if you start to see it not inflating, check to see if it's too much flow? I don't think that salinity is going to make that big of a difference, but stability is key, go slow and it'll be fine, they're pretty hardy.

My SG was at 1.026 and had drifted down to 1.022. I think that's pretty substantial. The lighting and flow hasn't changed. But ya, I'm back up to 1.025 as of this morning so hopefully it will be back to normal soon.

Trachy looking better today! Looks like it will be back to normal soon.
