A long time ago, I liked to get up in the middle of the night to look at the fish tank, in addition to watching the whole tank of sps fluttering hair, my favorite is the fluorescent color that faintly glows under the blue light, but it is very strange that as soon as I turn on the white light, it becomes ugly yellow
Later, after a long time, I learned that those were fluorescent proteins, most of the fluorescent proteins are green, and 90% of the SPS varieties in my fish tank are, and then purple, then red, and at least positive yellow.
My initial goal was to be able to see the color of sps under the white light can also be very dreamy, the so-called dream, is close to the color of jelly, because at that time I felt that only the sps to be dead, until the color of the backlight before death is the most beautiful, but this "do not care about the long day, only care about the once had" cultivation method, let me lose a lot of the best, some can not find back.
Later read some articles to know some stories about fluorescent proteins, in fact, corals to develop color, must be fluorescent protein, and fluorescent protein, as the name suggests, is under the low wavelength light source, will show the color of fluorescence, that is, 400 ~ 500 nm wavelength of the light source.
But the color of fluorescent proteins, it is easy to be covered by zooxanthellae (that is, symbiotic algae), the color of symbiotic algae is yellow-green, in many times, is the so-called coffee color, in order to remove symbiotic algae, KZ founder this seawater doctor invented a method to control the number of symbiotic algae, KZ several cans of products, there are added to remove symbiotic algae chemical components. This method is called color washing, that is, the symbiotic algae of sps is washed off and becomes a color close to white, so some green sps will become yellow after washing, which is also because the coffee-colored symbiotic algae is removed, leaving some green fluorescent protein, and green fluorescent protein is very close to yellow when it is very rare.
And symbiotic algae and fluorescent proteins, are present in the sps of the co-meat, that is, the sps of the tissue inside, sps of the tissue has an inner and outer layer, generally speaking, the symbiotic algae will be in the inner layer, fluorescent protein will be in the outer layer, so sps more fluorescent, need more fluorescent protein to work, but how to increase the thickness of the co-meat? It is necessary to rely on symbiotic algae to provide nutrients to the sps body, so that the fluorescent protein has more place to reproduce.
Therefore, early SPS breeders use HQI, because the light of HQI is very strong, one can make sps excite the number of fluorescent proteins of the body, so as to protect sps from the destruction of strong light, on the other hand, when the light becomes stronger, sps itself does not need too much symbiotic algae to produce nutrients, because in the case of strong light, it may be 1/10 of the original symbiotic algae can produce the original number of nutrients.
But this method must have a sequence, that is to say, in the case of a thick co-meat, and then enhance the light, reduce the number of symbiotic algae, at this time the fluorescent protein must increase, then sps will begin to develop color.
But in fact, as long as the number of symbiotic algae is reduced, the number of fluorescent proteins can be increased without using strong light, which is the most basic principle of the KZ system, to be honest, many people make sps very white and thin, but do not make up some elements to make fluorescent proteins absorb, so that sps lose symbiotic algae to provide nutrients, and finally will albinize to death, which is the wrong order.
So how to make the co-flesh thick sps remove symbiotic algae? In addition to the color washing method mentioned above, there is also a method, that is, to reduce the organic salt, reduce NO3/PO4, and destroy the living environment of symbiotic algae. Then slowly increase the brightness of the light. (Or increase the number of hours to turn on the lights)
However, as soon as the NP is lowered, the common flesh of sps will become thinner and will change into the color of Lin Daiyu! What we want is the color of Yang Guifei, so it must be high input (nutrition) and high output (PO4 & organic salt).
My own experience: it doesn't matter if no3 is high, but PO4 must be low, and when PO4 is low, the organic salt will decrease, or if the organic salt is low, the PO4 will become lower.
Methods to reduce organic salt are algae tanks, honey, rowa, but many people also use adding alcohol and vodka, so the method lies in the individual
I am constantly increasing the source of nutrition, increasing the source of pollution, making the SPS black, and then making the organic matter and PO4 lower, my goal is to make the fluorescent protein continue to increase and shine, so that the SPS appears saturated and thick color, which is currently about 70% of my ideal, so if it reaches 80% in the future, I will share another experience when it is even higher
