Thanks to everyone who left good reviews.
It’s good when the reef is thriving. But I would like to talk about failures.
When 4 years ago, due to poor-quality sea water, the whole system collapsed, it was decided to abandon natural sea water in favor of synthetic.
Then I visited the house of my friend with a fantastically beautiful SPS reef based on the Korallen-zucht system.
It was decided that I want such colors for my new reef. A month later, I was on vacation in Germany and drove into Korallenzucht and saw everything with my own eyes.
There, a starter kit for the coral system was purchased. In another store, 2 T5 lamps were purchased, 4 lamps each (a total of 8 lamps).
3 years of failure. Not a single forum and none of my friends could understand the reason.
After placing the test frag, the first 2 to 4 weeks passed perfectly, the polyps were all open, then necrosis suddenly began and within a couple of days a white skeleton remained from the coral.
Tests on my water showed that everything was fine with the water, it means something with the equipment.
One of the friends suggested that this is most likely due to electricity in the water. It was difficult for me to check this, so I replaced all the pumps in my tank, but that did not save me.
I decided to switch to another system - Tropic Marine. But here I was waiting for the same failure with a couple of fragments obtained for the test.
In October last year, when I was ready to give up, my son, knowing how much I love this hobby, invited me to speak with my guru, the owner of one of the shops, the dealer of Korallenzucht, for the last time.
After thinking, he pulled out the ground from his demo aquarium and gave me a try. That helped!!! But RTN began on some of his corals. He urgently had to return the ground probe to his tank.
Later they told me that the source of electricity in the water is a lamps, and that was the only thing that I did not change. By the way, the lamp was Chinese, as I later understood with a weak starting transformer.
If this information helps someone, then I will be glad.
Great find on the electrical source!
I'm very curious as to how the electricity made it from your lamp to the system's water. What path did it take? I'm a marine electrician / electronics technician by trade so I'm naturally curious about these kinds of things.
