How long has the tank been up? Tank size? Light schedule? A little bit more information would be nice as the parameters look okay

The tank is running 1.5year 160gal. Im running saxbys with 4 hydra 32 hd + 4 t5. Its kind a slime on my corals and losing tissue

White light picture? Brown jelly disease maybe

Edit:

Actual Millepora sp. or Acropora millepora?

Sorry not mille i wnated to tell pocilopora. It seems like brown jelly disease but on hard tissue corals??

Maybe? Kinda looks like it, maybe another "brown stuff" disease, maybe just cyano on dead coral in blue light, hard to tell with all the blue

If you are not aware of any temp, alk or nutrients spikes lately I would do the following:
-check salinity and make sure to calibrate ur refractometer.
- run polyfilter
- run carbon and change every few days for couple weeks.
- run phosphate reactor
- do couple large water changes 2 days apart then weekly large water change for a month
-decrease lights to avoid stressing corals more
- send water sample for ivp testing before doing above to hopefully pinpoint a cause.

That's still blue. Kinda tending more towards just cyano now though

How are the magnets in the tank? None of them have blown have they? (Unlikely with Acros being fine) but best check anyway just incase!
