Marine fish disease is very common, but for novices, really do not know how to treat their own fish, this article is my personal experience and online information of the combination of the combination of the version, if there is something wrong with you, please include and point out, at the same time, the coral hair color problem is also very troublesome for aquarists, Xiaobian also sorted out Oh today!
Let's start with the most common questions:
1 White spot disease
This is an ectoparasitic disease of scaly fish, very common, and it can be said that we are more or less present in our tanks. This parasite draws nutrients from the host to reproduce itself, they will not take the life of the host unless they reproduce in large quantities, they will only weaken the constitution of the fish, and the fish with reduced immunity will be like a person with AIDS, and will be plagued by other diseases and eventually die.
Solution: None! Once the fish are infected with white spots, we can no longer completely eliminate them, even if we disinfect them with high concentrations of copper sulfate, boiling them in high temperature water will not completely kill its fullness. Quarantine is a self-deceptive move. Wildfires burn endlessly, and spring winds blow again! It's all too appropriate to use.
But you don't have to worry too much, as mentioned above, it is not the culprit of dead fish, maintain the right attitude, carefully take care of the water body, white spot disease does not cure itself (not disappear).

Algae infestation
The main tank is rampant with evil algae, which affects the appearance, not to mention some of them will also hinder the growth of corals. The appearance of algae infestation is caused by excessive nutrient salts in the water body. Some people here will say: the nutrient salt in the water we measured is very low, how can there still be a lot of hairy algae on the stone. In fact, the value you measured is correct, the fault in these nutrient salts is not only in the water body, your filter media hides a lot of nutrient salts. They are slowly released from living stones or filter media, absorbed by algae and cannot be detected.
In a perfect aquarium, the area except for the algae tank will not grow algae (excluding calcium algae)! Because the early stage of the perfect explosion of algae, the middle of the good control, the later stage will not worry (hanging depressed ~) the late emergence of algae problem solutions: add adsorption system, such as algae tanks, nitrification and phosphorus removal equipment, reduce feeding, water change, replacement of filter media and other techniques combined, can achieve a certain degree of inhibition. Here is a little note: all filter media except living stones must be replaced regularly to ensure the health of the system, and living stones that have not been illuminated for a long time should also be replaced regularly. warn!!! Do not reduce the lighting !!! You're starving the algae and the corals are starving to death!!!

Ghost hand
It is a small but extremely fertile anemone, and many fishermen have endured its torture for a long time. Most of the sources of the ghost hand are brought by themselves on living stones or brought into the system when they enter corals. There are also a few people who are brought into the system because the fish has its spores stuck to it, which is almost impossible to prevent and difficult to eradicate. When the outbreak of ghost hands is the most serious, even on fish!
Control method: biological therapy. It is said that some creatures can eat them, such as black-fingered sea hares, mint shrimp and some butterfly fish. Butterfly fish are the least reliable, they can easily change their recipes and hit your beloved corals instead. Mint shrimp will also change the recipe, and before that some black-hearted merchants will fool you with mechanical shrimp. The black-fingered sea hare only eats the ghost hand, and the ghost hand will be starved to death if it is destroyed. But this sea hare likes to swim ~ often hanged by the wave pump. Dead, die, this sea hare body hides toxins, will be released into your tank in one breath, causing unnecessary losses. Biological therapy is a thorny future.
Drug therapy: I am the least recommended for drug abuse, and I am like a Chinese doctor. There are medicines for killing ghosts on the Internet, and you can choose enough according to your own needs. The effect is outstanding, but it is difficult to say whether it will have an impact on the system in the later stage.
I named it photoelectric therapy: about two years ago, a company enhanced the laser pointer for teaching, which can light a business card. Now further strengthened on this basis, it is possible to light cigarettes 8-10 meters away. We can use this small device to control the number of ghost hands. However, when purchasing, you must pay attention to the laser that must output more than 3w and the blue spectrum. Light decays violently in water, and at a certain depth only the long light wave spectrum can pass through. So it works best with blue. It must be shot into vertical glass when using it, and wear anti-laser glasses! Targets within 40cm of a good focal length will turn into ashes in 1 second! It also removes ugly creatures like snails, worms, crabs, etc.
No matter which method is used, do not completely eliminate them with zero tolerance, they have a meaning of their existence. Just control the quantity.
In the following article, I will focus on analyzing some common LPS problems.
4 Coral deboning
I believe that almost all seawater players, including me, have encountered the problem of LPS deboning. A small part is caused by excessive water flow, and there are other reasons, especially individuals who are still in good condition, but after several feedings, they have deboning. To be honest, the high nutrient salts of water are not easy to kill corals directly, and will only stop or slow down the growth rate of corals and make them regress their beautiful appearance.
Let's first analyze the causes of deboning.
1 Rapid water flow can cause deboning. This is easy for everyone to understand.
2 Self-depletion causes deboning.
This is very difficult to understand, let me explain it to you. First of all, everyone knows that calcium can be dissolved by weak acids, and calcium can settle in a weak alkali environment. Therefore, corals need a weak alkaline water environment in order to grow bones. Secondly, corals are also animals, and they need to obtain organic food, which must be absorbed by itself, and digestive juices are acidic. In addition, almost all living organisms on The Earth need to use calcium to maintain the pH of body fluids. In this way, we know that corals will digest their calcium bones when not fed, and if they are over-fed, corals will break down their bones due to increased acidity in the body. The bones of LPS-linked polyps are mostly flaky, and the surface of the bone tissue becomes rough and has jagged grooves after being destroyed, which can easily cut through the fragile polyps of corals and cause deboning.
Workaround:
Phenomenon 1: You only need to move the coral individual to a position where the water flow is slower, or change the direction of the water flow to avoid blowing the coral body directly.
Phenomenon 2: Reasonable feeding is a compulsory course to raise LPS, we should understand their respective growth environment and living habits, the attitude of equal treatment is unscientific. In addition, through the above, we should recognize the importance of trace elements, LPS also need trace elements! In addition to calcium and magnesium, etc. are needed to synthesize bones, the growth and repair of the fleshy part requires the consumption of many trace elements.
Who of you has ever seen a deboned LPS in an SPS cylinder? Unless it is bitten by a fish
5 Coral polyps fester
This is also a common problem with LPS, where a small injury on the coral body develops into an overall ulcer or a multi-head coral dies with one head and the other head dies.
The reason for this phenomenon is that the coral body is injured in the process of collection, trading and transportation, and after reaching the player's hands, the wound deteriorates due to poor water quality. The water quality mentioned here does not refer only to nutritional salts, but also lays a special noun explanation article in the early stage of this relatively large article. Ulceration is mainly caused by microorganisms in the tank. Bacteria invade coral wounds to break down polyps from the inside, causing ulceration.
Solution: Sterilization! Providing the necessary trace elements, vitamins allow corals to repair themselves. Of course, some corals that are too badly damaged cannot be rescued.
6 Coral bleaching
Coral bleaching is a common phenomenon in the daily maintenance of corals. There are many causes of albinism, and we do not need to eliminate them all when we want to solve the problem of albinism.
1. Temperature
Changes in temperature will cause corals to bleach, LPS and SPS to be more pronounced. It generally manifests as occurring below or above corals adapting to temperatures for a long time (more than 5 days, temperatures above 30 degrees or below 22 degrees). This is due to the fact that corals stop metabolizing at low temperatures, and zooxanthellae in the body cannot obtain enough carbon dioxide and die in large quantities. Or at high temperatures, the coral body metabolizes too quickly and the zooxanthellae metabolizes a large amount of oxygen so that the coral cannot withstand it and thus excretes the zooxanthellae and bleaching.
Solution: Temperature control equipment, not much explanation. Players with halogen lamps must carry a chiller.
2. Nutritional salt
Everyone knows that corals in water with high nutrient salt content will fade their original beautiful appearance into coffee color. It is not known that the brown coral will eventually turn white for a long time. The increase in nutrient salts will stimulate zooxanthellae to multiply and make corals become coffee-colored, and the massive amount of zooxanthellae metabolizes huge amounts of oxygen to poison coral oxygen and thus become smaller and smaller. Zooxanthellae in the unextended coral will die due to the lack of light, coral bleaching...
Solution: develop good water change habits, establish nutrient salt adsorption equipment, feed a small amount...
3, Irritating bleaching
It can also be called pseudo-bleaching, because the coral body is too disturbed by the outside world, and the self-protection enters a semi-dormant state. During this process, the coral will excrete a part of the zooxanthellae, which is not really white, but the color is a little lighter.
However, it is worth mentioning that many drugs can cause irreversible damage to corals. Long-term use can cause corals to die.
7 Gem flowers cannot be raised for long
Gem flower is a very common coral species in LPS tanks, it will be several times larger than the size of the bone when it fully extends the body of the hydra, and the hydra body sways in the tank with the flow of water is very eye-catching. But this coral was once called a "flower arrangement variety" by fishermen. As the name suggests, it is impossible to maintain the state for a long time.
In fact, the gem flower is not a short-lived species, but the basic value of the water body of the general player's LPS tank is not up to standard.
By looking at it, we can see that the mouth plate of the gem flower is very small, the tentacles are also very short and there is no grip, and it relies on filtering some debris, photosynthesis and trace elements in the ocean to maintain its own growth. At this point, we understand that debris is a suspended particle, photosynthesis we can easily guarantee, but new and lazy players will not take care of the trace elements in the cylinder. So much so that the gem flower is crowned with notoriety.
After reading the above content, everyone should understand the importance of trace elements and the scope of water quality that need to be strictly controlled. Raising corals at a reasonable level is also the most cost-effective way to raise them! Let's take a look at how you can make your coral hair color better!
How to make your coral hair color
★
Most SPS breeders know that sps will turn brown for a period of time after purchase, which is very ugly. It takes a while to recover, so what factors are needed to restore these original colors?
First, explain the formation of coral color.
The color of coral is a kind of "protective umbrella" used to protect the zooxanthellae on which it depends from being secreted by strong light. By adding the color temperature color of the received spectrum to the fluorescent protein, which is added to the trace elements needed to produce pigments, the colorful corals we see are produced. After we know the causes and needs of coral color formation, we will understand:
01
Powerful Lighting Systems Corals need powerful light to generate colors, so strong that they feel threatened and need to use pigments to protect themselves. And this powerful illumination in nature comes from the sun. We know that sunlight contains the entire spectrum, which is the most basic basis for producing a variety of colors. At present, the lamps that can simulate daylight-like illumination are only halogen lamps, don't take T5, LED here, this conclusion is not under me. At sufficient light intensity, corals begin to have a desire for color under a full spectrum.
Enough nutrition It is not enough to have desire, as the old saying goes: full of warmth and lust. If you don't eat enough, everything is in vain, so the corals should be fed. There are two kinds of feeding mentioned here, the first is the aforementioned light, which must consume 75% of the energy consumed by corals every day from the conversion of light energy. The second is vitamins and trace elements. Without enough energy for it to grow, they cannot produce fluorescent proteins normally, and they will eventually be killed by powerful light.
Special trace elements The conditions for coral hair color are already in place, and the necessary elements for the formation of pigments are almost there, these elements are currently known to include potassium, iodine, iron, boron, etc., their content can change color, although the main factor in the production of color lies in the spectrum, but if you adjust these color elements, you can generate colors near the spectrum.
The above discussion tells us that the water of sps is still very deep, and we need more research and experimentation to get the mysteries of nature.
