How long for candy canes to recover?

[Zoa_Fanatic]

I have some candy canes that have recently become super super mad for some reason. They deflated one day when I raised the pH of the water by 0.2 over about three days and now have slowly been reinflating during the day but looking like crap at night. Before and after pics attached. Any idea what the issue is and when they could possibly, if at all, recover to pre-mad state? They have been in my tank for 8 months. Good photos are months old. They've gone from nearly dead (2 heads) to nearly 20 mouths now in that time. Not sure why my images are upside down and I can't change it.

Update: Photos of them looking bad are after my lights have gone blue I just switched them back over for pics. They inflate a little during the day.
