LPS Coral (Acans and a Scolymia) are receeding. What do i do?

[Blitz99]

i have some stuff receeding. they are under the stock PC lights on a nano cube. the ones that are receeding are 3 acans and one scolymia. my other lps (euphylia) are healthy.


what could be going on? what sort of treatment would i use? trial and error or is it a pretty easy cure?

is it a lost cause? one of the acans is about gone.

IMHO, they shouldnt be under stock anything in a nano cube..

Water params?
Alk?
Ca?
Temp?
SG?
Water source?
Any algae?
Critters?

Need a lot more info for any type of a good response.

Your lighting would be considered a Very low amount of light. Also, go through matt's checklist & post your parameters.
