I got a war coral about 2 weeks ago.
I mounted it lower in the aquarium away from the powerhead. I didn't have a PAR meter at the time, but since got one.
After about a week, I noticed that the faces of the coral that were facing up started to look like they were losing coloration and the faces pointing down seemed to be holding color alright. So I guessed that I might have the lighting too high. I since lowered it and a week later things are continuing to get worse and it appears some of the green spots recently decayed.
I measured it now, and the lighting is 80 PAR. I tested the prior PAR by changing the lights back to their old settings and it was probably in the ballpark of 130.
I run a 10 hour light cycle with 1 hour ramp up and ramp down with an AI Blade Grow and Glow combination.
Water parameters all seem good.
PH 8.3
KH 8.0
Mg 1280ppm
Ca 410ppm
Nitrates 4ppm
Phosphates 0.02ppm
Temperature 78
Looking on thoughts if there is anything else to try here. No other nearby corals, but there is a zoa and green star polyps up higher in higher flow that both seem to be doing fine. The green hair algae has been getting somewhat worse over the past two weeks, not sure if that could be affecting things.
Attached is a photo of it currently.
