Need advice on corals

Hello,

My tank is well over 1 1/2 years old. My lighting was changed out about 3 months ago which are VHO's. My corals in the tank are fed a diet of phyto and cyclopeeze. I do monthly water changes and my tank params are normal.
However I noticed that the corals are no longer as brilliant as they use to be. Additionally, one of the corals looks more white than anything which I know to be an indicator of zooanthelle dying. Is there any way to recover from that? Additionally, most of my corals look more brown in color than their natural green, purple, pink colors.
I use RO/DI water for water changes and it doesn't appear that there is an algae bloom in my tank.




Dull looking hammer coral


Overall tank shot. Let me know if the tank looks healthy or not?


Thanks
Dave

I too am experiencing a form of coral "reduction" for lack of a better term.
They are all still alive, but seem to be receding in size. I am referring to a pulsing xenia, zoa rock and several button polyps . water params have been stable for months, with the exception of temp being a little higher now due to summer heating. Would temps around 82-84, for several hours a day, cause softies to decline?
BTW, a hairy mushroom and all other critters are doing fine.
25 gal. eclipse 2 tank with PC upgrade. 8 months up and running.
SG - 1.023
tests for all the usual - amm, trates, trites ets.. show nada, calcium around 400, alk - good, ph 8.2
