While I was gone on a mini vacation, my light somehow switched to a different setting, in which it had 100% on both channels. Wayyyy too bright to say the least.

The corals looked horrible and I thought they were all going to die. But I blacked the tank out for 2 days, and then introduced them to sunlight for the next 4. Now the lights are on 50% of what they usually are.

So should I reduce the temperature? I don’t think this is the problem though.

Also could a lack of nutrients cause white coloration?

They probably got sunburnt, or the aquarium equivalent of that. If corals get too much intense light too suddenly, it can stress them.

After a few weeks of 50% light, slowly increase it a little bit every 2 weeks. This will allow you to increase the intensity slowly over time and they shouldn't go into shock.

How warm is the water?
Try to keep the temperature around 24-26C (75-79F). It's ok if it goes up to 27-28C but don't let it go higher than 28C (82F).

Lack of nutrients won't cause the coral to fade. Corals naturally grow in water that has a very low nutrient level and they struggle when the nutrients (ammonia, nitrite, nitrate, phosphate) get too high.

Yes, that was my thought as well. (Aka getting bleached)

Yes, that is what I’m doing with the light. It’s day 5 (or 6?) of having it on 50%. After the one week, I’ll bump it up to 75% of what it was, and then the week after that, 100% of what it was before.

The water is around 81F. I guess I could turn it down a tad and see if that makes them improve any.

Removed algae from the digi. You can also see the new buds on the cloves.

FTS:

Thinking of adding more rock in the back right corner.

My Duncan way be a rare variant. As you can see, it’s clearly different from anything found online. (Even from the vender I bought it from!)

Because if you look at these other pictures of Neon Stem Aussie Duncan’s, they look nothing like mine:

(even the ones from POTO!)

Here’s mine just for comparison:

You can also see all the new heads growing in.

New coral came in yesterday. (POTO Rose Tip BTA, Utter Chaos Zoa, Purples)

Ok, here again, I’m using the crappy iPad camera to take these:

Im also using an orange medicine bottle so I get some color, and it’s not all blue.

All of these actually look pretty dang close to what I’m seeing, except for the big colony, it’s not that green.

——-

The BTA did slide off the top of the rock and onto the side, but I think that’s because it was too much flow? Looking much better now. If you zoom in, you can see those nice bubbles!

(New zoas are in the second to last photo - red single polp and then the frag next to that. The BTA is the first pic)

don't you already have an anemone?
if yes, be careful they don't fight. normally it's best to have just 1 anemone per tank

Hi,

I would watch the placement and amount of coral you are adding. Some corals will fight (sting) and this could cause issues. In the past whist observing my S/W tanks at night (use a red light), I did see this happening.

No, that is my Duncan:

Yes, I am aware of this. That is why I have the tank setup the way I do.
