Shrooms slowly losing color

[mushy coral]

I got this godzilla bounce for nearly a year and it been doing good both in my previous frag tank and my current mixed reef tank until few days ago it started to shrink and expell zooxenthalae.
Tank parameter:
Kh 8.3
Mg 1450
Ca 450
No3 10
Po4 0.03
Temp 25.5-27C
Salinity 1024sg

I got a jawbreaker and an og bounce completely bleached this way. The simptoms are similar: suddently shrink, wide mouth and expelling zooxenthalae. Those 2 previous shrooms bleach rapidly in 3-4 days while this godzilla seems not yet to lose color. Although it push out the zooxenthalae 2-3 times last few days i have not seen any losing in its color around its mouth. I got water parameter in checked, i reduced my lighting and i put it in a spot with less flow after i clean the wavemaker (this wavemaker started to make stronger flow after cleaned). So i really dont know what could cause this. Its not losing color but also not fully inflate for days. All other corals in my tank including hammers, acans, blasto, elegance and other shrooms are fine
These are images on november and today

It’s up now.
Do you regularly run phosphate at 0.03ppm?
With test margin of error that could be 0.00ppm just as well.
Why run it that low?

This is when it shrinks

Does it only shrink, or can it expand?

Does it only shrink, or can it expand?

Did its flow or light change, or was it moved?

It srinks down its sized by third. Havent seen it fully back to like it was last month since days ago

You’ve changed its light and flow.

Some take weeks to reset their photosynthetic processes.

If all other corals are not affected, just give some time with no changes

0.03ppm phosphate is too low for me unless I know my test was very very accurate, which for most, are not.

The flow changed cause i pulled out the wavemaker and cleaned it so it was a bit stronger than it was so i adjust both the wavemaker and the pump to make the flow closest to when it was. After adjustment the corals that on my sandbed near the godzilla are perfectly fine except the godzilla itself, it srinked on the day i cleaned the wavemaker. so i moved it to a less flow spot.

Its 0.3 which i kept it that way for few months. My typing is just suck lol

Likely your issue.
PAR may change when you move.
I’d do nothing.

Ok, that’s better.

Since i moved it both flow and PAR changed so im gonna leave it there and if is gets better then great but if it gets worse what could i do? I got coral revive available and some tanks that i could move it to.

Revive just going to stress it out.

Some corals shrink and die out after years with no apparent reason.

If every other coral is doing well except one, there may be nothing wrong with the environment.

Dang i just got this one under a year from 3cm to nearly 10cm in diameter now. Would be really sad if it dies. On the bright side it did leave some of its offspring on the frag plate XD

Doesn’t look unhealthy to me and great colour.
Has spectrum changed?

One pic looks more blue than the other, at least, in the pics.

Been few days and its keep getting worse. Srink even more and slightly lose color near its mouth
