My FT receded and I noticed dark spots with dark stringy things attached to them. I dipped in Luogol's and coral RX and things seem to be stabilized but I noticed a dark spot on it in the pic. Is this brown jelly or something else? Should I frag that receded part?
I noticed the Tyree Pink has a hole. Doesn't look like something burned it. Any pests that could possibly cause this? Should I dip the Pink? All other chalices are fine. Thanks in advance.

It could be alk swings, salinity, temp, low mag., ph Those are the usual culprits when it comes to receding or chalices dying. I'd check and test all of them a few times over the next couple of weeks and write down the numbers. Also changing out bulbs or putting in a new lighting system. adding any chemical media can disturb the balance in a tank and affect growth and stability. It's a process of elimination and hopefully you'll catch what's wrong before you see any more receding. Good luck.
