It's a big problem for newbies, why do my corals always shrink, deboned, vilified, and die?
That's because you haven't figured out what corals really need in the tank, so today we're going to take you to see what corals really want!
To raise corals in the sea tank, the first thing is, of course, to create an environment suitable for their survival, and water quality is the most basic.
In addition to ensuring the basic salinity and temperature, we need to pay more attention to the nutrient salts and trace elements in the sea tank.
Fish and various organisms swimming around in the aquarium will metabolize and release ammonia nitrogen waste, but these in a stable aquarium system, it will not cause much impact, but it still needs to be tested regularly.
For corals, the calcium and magnesium KH in the sea tank are the most important, especially LPS, SPS, some corals that need a skeleton, we must maintain these three values at an acceptable level.
Because corals use calcium from seawater to produce calcium carbonate bones, if you want the corals in your tank to grow healthily, they must be able to get enough calcium in seawater.
In the natural seawater environment, the concentration of calcium ions is about 400-450 ppm, and the ideal concentration of our sea tank is the same, but the corals maintained in the sea tank at about 350 can also grow normally.
Don't think that more calcium is better, and it is wrong to frantically increase the concentration of calcium ions for the growth of corals.
Because the amount of coral absorption is also limited, too much calcium ions will make the coral burn its head, and it will also produce too much calcium precipitation, affecting the life of our sea tank equipment.
The health and bone growth of corals will also be strongly affected by the pH of seawater, and the pH value is directly affected by kh, although it is very circumferential, but the increase of kh value will enhance the buffering capacity of seawater, and enough kh can prevent the phH from producing a fatal decrease, resulting in acidification of seawater.
Although ph is the murderer who directly affects the biological state in our sea tank, maintaining the content of kh to restrict ph is our correct way to deal with it.
If you want to ask what is the role of magnesium in the coral tank, then I will tell you first, it is the third rich ion in seawater, the most important role of magnesium is that it and the coral cylinder play a role in the balance of calcium and alkalinity interaction, whether it is natural seawater or seawater in the sea tank will be full of calcium carbonate, if the lack of magnesium elements, then excess calcium ions are easy to precipitate, magnesium ions are through the combination of carbonate ions and provide buffering capacity to prevent this from happening.
Corals are moved from the ocean to our tanks, although they do not have the vastness of the sea, but they do not have to worry about the dangerous environment, so that they can eat and clothe.
Just as humans need the sun, corals also need light, but different corals, they need a lot of light flux and light intensity.
We have to understand where this coral grows in the natural environment, corals in shallow water are adapted to high-intensity long-term light, while corals in deep water have less demand for light, and high-intensity light will make them uncomfortable, causing harm.
We can place corals with little light requirement in a darker place under living rocks. Corals that need strong light can be placed close to the water and baptized by light.
A pool of stagnant water will bring decay, but we need to flow water in the sea tank where we feed life, and in the natural environment, the water flow of the ocean never fixes a direction, but randomly forms turbulence, which needs to be left to our waves to create.
And with the flow of water, to prevent the accumulation of harmful substances, the small organisms in the seawater plankton to the coral's mouth, which is our main purpose.
But we need to pay attention to the fact that, like light, different corals need different water flow, durostyle corals can mature stronger water flow, and LPS will be because the water flow is too large, resulting in polyps cut by coral bones, so we should reasonably place the location of the coral, considering its original living state.
Finally, corals need to be fed regularly, although except for non-photosynthetic corals, most of the rest of the corals can provide energy through the photosynthesis of zooxanthellae, and there will be tiny plankton in the tank for them to eat.
But if you want corals to grow fast, it's not enough, because in the natural ocean system, the huge flow of water will constantly provide a lot of food, and our tanks have limited water, we want corals to eat, we have to provide additional supplies.
The above four major appeals, are known to aquarists, but it is easier to ignore a few points, although corals are animals, but they are suffering from being unable to speak, when they successfully express to you, it may be a time to be in a poor state or even dealgae, so we must regularly observe the corals in the sea tank, if there is anything abnormal, then we must think about which step is wrong or forgotten.
Well, hurry up and pay attention to the sea elves, and take you to play with the most beautiful sea tank.
