Struggling Frogspawn NEED HELP (pics)

[Patrick Cox]

Need your help here please. I am finishing a new build and preparing to transfer some corals from my old tank to my new tank and now some of my LPS corals don't look that great. The polyp extension is very minimal and the skeleton seemed to be hardening on my Frogspawn. I tested my alk and it was very low. I then began to drip some reef builder (Seachem) to raise my alk and now alk is in a better range. (Alk was around 4.5 dKH maybe 3 days ago and now I am up to around 9.5) Calcium was around 400 and Mag around 1600.

I think the reason the alk dropped is because I removed all of my live rock because I had aiptasia and flatworms that I was trying to kill. I was handling biological with some bio balls that I put in the sump about one month ago to seed in anticipation of removing the rock.

I can't tell if the corals are improving or simply holding their ground so I would appreciate input/thoughts on how to proceed and what you see in these pictures.

Also, should I just go head an move these corals to my new tank? I believe the tank is now cycled and I have been "cooking" my pukani rock for about 2 months.

Thanks for your help!

Here is my elegance. It has been pulled back in the skeleton for several days.

Here is what both corals used to look like...
