Hello Holger83,

Sorry, I don't have a led experience.

as shown in the figure (yellow circle), is usually used to identify the nutrients of water quality. It is a good coral for judging water quality.

The newly grown part of the right side of the coral looks good. The tissue is not deep with a bit of blue and some green, but usually this is normal, and the coral in the upper left corner performs very well.

The two pictures look like the water quality is OK. I don't know if the photo is a led relationship, which may affect the discrimination, but it seems that the coral is healthy and beautiful, except for a few coral tissues.

Like G. say the possible factors, or try to change the elements in a balanced way with a small amount of water

Or move the coral to the top

Or increase the white light illumination time of led

If the water quality NP is good, it does take some time for some corals. In a coral position in my tank is above, it took about a month to start slowly changing.

Then I will advise you to maintain good water quality, slightly increase the white light time, and let the time improve the coral. Please pay attention to the health and appearance of other corals.

17. What is the basin decorated with (live stone/ceramic/sand)? What is the age of these materials?
Ceramic and CaribSea LifeRock,

is this part of the reason?
What brand of sea salt is used?

The most important thing is to get a higher precision PO4 instrument, and really know that the value of PO4 is good.


I re-read the picture (#2). In the case of a lot of water, the adjustment of the element Kh requires special care, which may lead to the phenomenon of TN at the bottom of the coral. Most of the corals look like the tissue is not light. Then get a more sophisticated PO4 instrument, and increase the lighting time, because I don't have the experience of Led, I can't recommend you to increase the strength of the led. If the control is not good, it may cause the coral to be hurt. I don't mean that Led is not good, I hope you Don't get me wrong.
