Not an expert but the change of color makes me suspicious of the light, did you change something in the lights ?

 

[Dj City]

Nope.
Those corals looked like the 1st pic for about a year. No tank changes. Over the past 2 or 3 weeks, they declined.

I'm changing my lights next week though.
I'm going with 3 ocean revive t247's

old bulbs?

what are you running for lights now

 

[Dj City]

Bulbs are not old yet.
I'm running 4 ATI t5's with a Fluval Sea marine led and a Current USA marinr orbit led.

I had a bout with flukes. I dosed the dt with melafix. this was about 3 weeks ago. I got it out with carbon and wet skimming.

The corals were declining before the bout with flukes though.

No water paramater changes.

 

[Jeepguy242]

could be the problem.... try some water changes to make sure the melafix is out

 

[Dj City]

Already did that.
Corals were declining before the flukes and before melafix.

 

[Vincent100]

Do you feed them ?
Also do you know your no3 po4
Wonder if your water has become to clean with the wet skimming and water changes trying to get the meds out ....just a thought

This looks like a chemistry issue. Melafix could have compounded the problem if the corals were already stressed. How often do you test, what kits do you use? How often do you do water changes? Do you dose?

 

[joao.malhadinhas]

Are you dosing any vitamines or aminoacids for corals?

 

[Dj City]

I test about every week.
I was dosing seachem fusion 1 and 2 but I'm about to start Triton method.

Prior to water change from the melafix, I had not done a water change in about 5 months.

I may do a large water change just before putting triton online.
