Supplement: 0.3 liters is roughly equal to 300ml.tank water purification capacity 370L, up to 350ml (using measuring cup)

Try to answer you - changing the water is to help restore, this situation is temporarily stopped adding activated carbon, first let the corals recover and then use Zeo's activated carbon, this time you can consider using 150ml or 175ml

Kh ca mg K+, please keep it as stable as possible

Characteristics: Bad/incorrect use of activated carbon, the surface of coral tissue becomes smooth, this is a feature that can be observed, and I dont know if there is any sorbent in the tank, if any Please remove it too

My experience is not very good, see for a reference

1. Coral has no PE 2. Smooth tissue, 3. Burning tip, do you observe from the picture

Yes, there are burning tip. U mean u just make water change more, and keep parameters more stable before add new active carbon?

Yes, you are correct, (keeping the water parameters stable)

I am sorry to hear this news, the coral situation does not look optimistic


1. What kind of salinity level, what kind of Kh.Ca.Mg.K+ level
2.Are you still using Rowa carbon? Do you use Zeo's activated carbon? And how much / how to use it?
3. What have you changed or done in the near future?
4. What kind of ZeoVit reactor flow value
In addition to the Zeo system, do you have to use some extra items? For example, adsorbent


Elemental ascension needs to be carried out at a slow rate, not too fast, which also causes the coral to be stressed (I don't know how you do it in this regard, such as the potassium mentioned in the near future)

My other feeling, because you are not using live rock, biology is not so stable, it seems that the system is very vulnerable, if the coral is healthy, then maybe consider using some dry sand, may be good

I don't know if this will help the TN phenomenon to be relieved. If it is me, I will do this.

Since the coral tissue has been eroded, I will completely remove the activated carbon and reduce the flow of the ZeoVit reactor by 1/2, try 10% water replacement, 3 times in 10 days (salt/temperature ensure consistency), and Try to keep the water parameters stable including potassium, Imitate those mucus by siphoning
Slightly turn Skimer to dry, Phosphorus should not rise during the period, keeping the basic dose of regular dose added

Minimize all fluctuations as much as possible, Let the corals balance naturally by changing the water
If an element is not balanced, this can also achieve a balanced relief.

Maybe other people can come up with some better different suggestions and help

I have removed all active carbon rowa as i said in the last thread. All parameters is more balance now.
Now i try to siphon and water changes. But i dont know what happen with my tank, someone talk me this is cyano, but i dont think so maybe this is something like a virus of coral.
Thanks for your help

Do you have those string like algae just on the corals which lost their tissue or does it show up on the sand / rocks also ?

From the pictures I would say those are Dinoflagelate, do you have access to a microscope ?

G.Alexander always has very good experience, thank you very much.

Let us try to replace the plastic hose in Sump, usually using silicone rubber
Some plastics are immersed in sea water to release some plasticizers.

Any plastic pipe, seawater professional use material, usually use "silicone", please also pay special attention to "fragmented coral board", quickly replace the tube at the arrow, if it is a problem
