Why can't I keep euphyllia anymore?

[Sick_man]

I have had euphyllia for about two years and they were all thriving. However last year they all started shrinking and never opened up the same anymore til this day. None of them died but they just held steady and did not grow. Its been like this for a year and the only corals that has been doing this is my frogspawns, torches, and hammers. Every other coral is doing good. Also have not spotted any flatworms either.
Here are my params: 8.4 alk, 435 cal, 1360 mag, 10 nitrate, .03 phos

got any leather corals?

Is your alkalinity stable? Phosphate is low. I would shoot for 0.05-0.1. There was a recent post with video showing someone mixing 1 tsp of reef roids in a tsp of water then using that thick slurry to feed through a syringe.

I removed them months ago thinking that was the issue. I am always running rox carbon as well.

my alk usually stays within like 8.2-8.8 it doesnt move much. Phosphate was sitting at .15 for a while even when they were happy. I recently started using GFO to lower it but that does not seem to be the issue either.

Let's see a pic of them

Thats the biggest my torch will get, it used to be huge back then

Have you tried feeding it?

I spot fed reef roids and dosed aminos. In my experience, I never really had a euphyllia that had a crazy reaction to food either.

A change in light intensity or spectrum?
Numbers, stability look good so that’s the other big driver.
What about flow? Have any clowns?
Doesn’t always effect everyone.
Very strange in a mature tank.

I've been running an ai prime with the exact same settings and I cleaned it regularly for dust.

Feed more. .03 phosphate is barely enough due to test margin of error

Full tank shot?
is that possible?
I just see one, so hard to envision.

I said earlier that I keep it at .15 but i only recently lowered it to .03 with gfo to see if that was the issue.

What is the flow like in that part of the tank. Euphyllia always tends to open up ALOT more with lower flow. When I turn the powerheads off in my tank to feed my octospawn and hammer get huge.

You said "Phosphate was sitting at .15 for a while even when they were happy". I interrupted that as phosphate was .15 and the corals were happy. So why lower to .03? Or am I reading what you wrote wrong?

The flow is low, I haven't changed it. I had a colony that was huge that grew out from a tiny frag but I sold it because it just started looking horrible

because they just started shrinking up for no reason. I wanted to see if phopshate being kept kind of high at .15 was the issue. I really have no idea what the problem is so I just tried that since I had some GFO laying around
