what recommendation could you give me to stop 🛑 rtn and coral bleaching is the current media fine ? The dosage is good ?

I do n’t know if you have tested it yet. Potassium also seems to be a very important element. It ’s also interesting to get a test pack of K + ~ 380 mg. (Special note: conifer skimmer) Certain carbon also seems to inhibit coral growth , What carbon brand do you use? The reactor flow rate is much lower. Due to the current loss of coral tissue, the flow rate is temporarily maintained. Please also obtain the correct reactor continuous flow rate again to clarify that it is correct. Using a small container, collect the reactor outlet for 30 seconds at a volume of x120 so that you can understand the flow level

[jacky]

We can do this first (# 2). Sand, it depends on your personal taste. In my tank, I use Zeo's dry sand, about 2 ~ 3cm, the sand particle size is about 2 ~ 3mm, biology / coral health / coral color brings me a good Results

Use crushed coral sand or aragonite. Do not use Live Sand in combination with the ZEOvit system. (When using wet sand, a combination of algae and cyano may occur.) Soak the material in reverse osmosis water for 3-4 days before use, and change the osmosis water every day. If the PO4 level of water is close to zero, then ideally sand. After that, gradually add sand, slowly adding sand in units of weeks instead of adding all at once

[jacky]

For your water tank, the amount of zeolite is about 1.75 liters instead of 2 liters. The continuous flow rate of the zeolite reactor is about 690 liters per hour (condition: if all corals are healthy)

Some carbon brands inhibit coral growth. It is recommended to use Zeo carbon, which is very good (I also use Zeo carbon, coral health is very good), for your water tank, the carbon is about 0.7 liters, use a net bag, passive flight, replace every 30 days

Carbon: 1. Some carbon inhibits coral growth 2. Overly aggressive ways also inhibit coral growth

The skimmer is really overrated for your system size and can be the reason for the light tissue and basal TN. As Jacky has already said, potassium is what I would check first.

k+380 by salifert test

[jacky]

If the potassium level is indeed 380 mg, it is very good, then we have clarified that it is not caused by potassium leakage. Carbon, what brand? What is the quantity and how is it used? The basic water parameter, Mg, are you adding it in another way to maintain the level?

[G.Alexander]

I had running the same skimmer on a system with a net water volume of about 1200 liters, the skimmer for my taste was already to powerful for this system size. I had to constant dose potassium and corals tissue was very light in conjunction with some basal TN here and there. The situation has changed when I switched to a different skimmer.

I would recommend to adjust the skimmer to skim as dry as possible for some time, additional you can do some additional water changes to refresh elements in a balanced way.

The ZeoVit quantity is also a little bit to high, lets reduce it to 1.7 liters with a constant water flow of ~ 700 liters per hour through the reactor.

Main water parameters are relative high, often a high salinity is the reason. Please cross check salinity with a different, accurate instrument and reduce the KH slowly to ~ 7.

What about the carbon, which kind do you use and how much, do you run it in a reactor ?
