Tissue recession on frogspawn??

[tjbrownie]

I was watching my tank today and noticed that my frogspawn hasn’t been extended as big for the last couple days. I had a major surface scum issue from my malfunctioning protein skimmer that killed an sps coral but my hammers extension hasn’t changed. Going back to The frogspawn there is a lot of bone on the stock that’s showing which I’m guessing is from growth but it’s extension is what I’m worried about. My DKH is 7.5. Ph is 8.19 and the salinity is perfect. Here’s a picture of it now

And here’s a picture from a couple weeks back

It looks reasonably healthy from where I sit.

Honestly it looks healthy to me, I wouldn’t worry. My hammer used to push huge polyp extension but now it’s been relatively low in PE as it’s gained more heads (sat at around 13).
