Frogspawn looking unhappy

[AVVITT]

Hi people
Below is a picture of my buzz light-year frogspawn. I got it around 4-5 months ago when it was 2 heads. It's now 6! It's ALWAYS been happy no matter what has happened in my tank. I had a massive alk swing a few weeks back, I've had phosphate levels of 2.5 and the thing never looked happier.
The last few days a couple of the heads look pinched in at a couple of points and the polyps retracted in places.
The only thing happened in the last 2 weeks is I was dosing Tropic Marin elimiphos (which is lanthium chloride) to bring my phosphate down which is from 2.5 to 0.05 in about 5 days and I've set up a bio pellet reactor.
Parameters are:
Alk 8.3dkh
Phos 0.05
Nitrate 10
Calcium 460ppm
Magnesium 1360ppm
Salinity 1.026
pH 8.0

Hard to tell much from the picture, is the tissue around the base of the head intact?

How are you dosing lanthanum chloride?

Yes the flesh is still fully intact. If you just imagine 2 of the 6 heads almost fully closed up and the rest of it fully out and fine but where it's closed up it just looks a bit off colour (brown) and shrivelled up.
I'm 99% sure it's not bjd because the polyp branches when extended are a light, golden brown, when they suck back in they go darker so the colour isn't too far from normal but it's not normal because it's never closed, ever!

I dosed the lanthium chloride using a syringe into the skimmer intake which I was told was the most effective. I worked out the amount I could dose initially could be up to 8ml for my tank bit I dosed 6 the first day, then 5 then 1ml per day for 3 days until the phosphate level was down to 0.05
The first picture shows the right side of the frogspawn which seem ok and pretty happy, the second picture is the left side which has one of the closed up heads. You can compare between the two contrasts.
Apart from closed up it seem ok. No bits coming off, can't see any parasites or anything actually wrong with the flesh
