What's going on here?

Can anyone tell me what's going on here, and what I need to do to stop it?

Tissue receding I’ve had this happend couldn’t save it basically moving it to try to help it made it worse

Agree, it’s dying…can you list your parameters, this may help you with the issue

If that happened overnight or so, munched on.
If over time, light too high and /or low nutrient availability.
Poor micro-fauna population. Dose phyto to keep these guys up. Other possibility, stung if someone like that close by.

Sal 36ppt
dKh 9-10(ish)
Ca 390-420
Mg 1500

Anything from the drug store is ok, yes?

Bump. Need to know if 'first aid' type iodine is safe, and if so, at what recommended concentration.
