Hello.
For several months, it has not been possible to reduce the level of nitrites and nitrates.

Someone has an idea how to reduce them?
Thank you in advance

Both levels are minimal and both do not have any kind of a negative impact to the corals or their coloration so my recommendation would just be ignoring them.

Slow growth is a different thing, the KH is a little bit low, lets increase it slowly to 7 – 7.5 keeping it there as stabile as possible.

The reactor flow is a little bit to low, 250 liters per hour would be ideal.

How often do you exchange how much water and are you able to post some coral pictures ?

Thanks for the answer. Our Zeovit specialists recommend that the KH levels are just low. In the store of the KZ dealer there is a magnificent aquarium with KH-5.5. At another, 6.0 and this is the most beautiful aquarium ever seen by me.
In regard to the water flow through the Zeolite filter. I measure the flow so, I substitute under a stream from the filter a 2-liter dummy. After filling 2 liters I calculate proportionally to liters per hour. But this is not the most accurate measurement. How do you recommend measuring the water flow through the filter?

In addition to SPS, I also have LPS .. 3 X Trachyphylia, Pink goniopora, Red Blastomusa, Chealice, Euphylia, Lobophylia, Fabia, Turbinaria reniformis and Hydnopora. All LPS feel good and all the polyps are open.

A KH of 5.5 is to low. You can measure the reactor flow by collecting the water from the reactor outlet for 30 seconds, than multiply its volume by 120 and you will get the exact output per hour.

Which additional products do you already own ?
