my understanding is that iodine is a very tricky additive to dose. there is not an accurate test kit for saltwater use. i have found all my leather coral to be very touchy on placement ,and some take a while to grow or even show that they are alive. if the leather was happy where it was before and nothing has changed it might just take a while to recover. i think something like kent coral accel would help it heal and protect against infection. if a chunk is starting to decay away, you may want to cut that piece off to stop it from spreading
