Hammar polyp thinning...

[Singspot]

Hi There, check out ky video, my 2 Hammars (out of 10) have theor Polyps "thinning". They are both growing very well and happy but for last 3 weekz i have noticed the 2 Hammars (yellow and the lilac/ bleeched looking Hammar) are becoming thinner. ..

My water params
Phosphate 8
Nitrate 10
Alk 8.3
Temperature spiked yo 82.8 F for a couple of days but are fine now between 77 and 79

Does anyone have any such experience, what could be the root-cause and suggested fix?

Not a soft coral (wrong forum).

The coral looks bleached, probably from the hot temperature.
All you can do is maintain the water as stable as possible, thats the only thing that can help it.
