"Foreword" I started raising ornamental fish many years ago, but at first I raised common ornamental fish such as goldfish, koi, guppies, and Maryfish. After I joined the job and became financially stable, I started to raise various aquarium pets. However, when I saw the live coral and saltwater fish in the fish tank for the first time in the provincial capital, I was instantly shocked and couldn't suppress my impulse, so I started my first "sea descent".
My first "going to the sea" started with clownfish and baby anemones, and then after watching "Finding Nemo", I opened two more sea tanks out of control. The first time I opened the sea tank, I encountered a lot of trouble, the second time I took a lot of detours, after my sea tank was stable, I summed up some small experience of "going to the sea" to open the tank, here, I am willing to share it with aquarium lovers, although I don't play the sea tank now.
The most important thing to play with the sea tank is water, and it must also be water!
It's the same water, but the names are different, one seawater, one freshwater. Therefore, water is the most essential difference between playing in a sea tank and raising freshwater ornamental fish. Think about it, it's the sea! It is said that the origin of life on earth is the sea, and it works if the sea water is moved into a fish tank? How can it not be important?
Playing the sea tank, the old aquarists say that it is easy, but the new aquarists are not so simple to play, but as for how difficult it is, it is not necessarily. Nowadays, the equipment is much more advanced, and the experience of the sea tank has become more and more popular, as long as you make a good start, it is really not difficult to play the sea tank.
A tank of stable seawater is the foundation of a sea tank. The marine ecology is extremely complex, so in the limited sea tank, we still try to imitate and simplify as much as possible. It depends on the approximate living environment, and on the other hand, it depends on the adaptability of fish and other marine organisms.
The composition of seawater is very complex, and there seems to be no simple thing in nature. There are hundreds of trace elements in seawater, each of which plays its own role and maintains the delicate balance of the marine system. Coupled with salinity, water temperature, water quality softness and hardness, pH and so on, not to mention rookie Xiaobai, it seems that you are not a marine expert, and you can't open a sea tank?
But for newbies, you don't really need to know that much. Because your purpose is not to study the ocean, but to open a sea tank that pleases your eyes. So, you just need to understand the core indicators.
Sea salt crystals
Here I have to mention that the sea salt that can be purchased on the market now, as long as the quality is qualified, the elements in the seawater are basically prepared, and they can be prepared according to the instructions, which can be similar to the seawater.
When we buy sea salt, we will also encounter good and bad products, so if there are conditions, it is a good choice to directly choose sea salt extracted from the seawater of coral reef waters, because it is more in line with the needs of sea tanks. After that, it is the control of salinity, which seems to be professional, but it is not difficult, as long as it is measured with a special salinity meter. Regarding salinmeters, it is recommended to use optical salinmeters, because they are simpler and more accurate.
Well, when the water temperature is 25 degrees Celsius, the salinity of the sea water is between 1.021 and 1.023, your first step - sea water blending is completed, sea water is the foundation, the basic conditions for playing the sea tank are in place, but this is far from all.
Playing with the sea tank, the water temperature cannot be ignored, it determines the state of the creature!
The temperature of the water is also an important indicator that cannot be ignored when playing the sea tank, and it will determine the state of the creatures in your sea tank. Isn't there a living thing and a fish in the cold Arctic Ocean? I'm sorry, that's not the kind you want to raise, so don't raise the bar.
In general, 25 to 27 degrees Celsius is the best temperature range for coral growth. There are many types of corals, so the degree of temperature tolerance varies relatively, but if the temperature exceeds the range of 15 to 32 degrees Celsius, the coral will die. As for corals, we'll talk about that later. Why do we mention corals here? Because corals can tolerate temperatures, marine fish certainly have no problems, so we use the minimum standard to define it.
Temperature also has a crucial impact on marine microorganisms, which determine the stability of a tank's seawater quality. They are mainly cultured nitrifying bacteria and anaerobic bacteria. There is no need to go into detail about the role of nitrifying bacteria, which convert excrement and food scraps into nitrate. Without this step, the build-up of ammonia and nitrite in the tank would have been a killer for the fish.
When nitrifying bacteria convert nitrate, anaerobic bacteria will break down nitrate. Nitrates are harmless, but everything is the opposite. Anaerobic bacteria decompose this substance into nitrogen gas, which is directly discharged, and a delicate cycle leads to healthy growth. In general, the presence of anaerobic bacteria is small, but it is not recommended for beginners to try to get on the NO3 remover directly. Because if you don't use it well, your sea tank will be destroyed.
The most common creature in the sea tank is coral.
Let's start with a few words about corals. Personally, I feel that corals are indeed a difficult point for novices to play sea tanks, because they are really demanding. As a community of plants and animals, it needs both plant fertilizer and photosynthesis, as well as foraging. As a result, it is generally difficult for corals to survive in artificial conditions for long periods of time.
It's just that there is no coral in the sea tank, as if there is no soul. The symbiotic fish that want to be farmed will also appear unhealthy or even die because of the lack of barriers. Of course, there are certain types of corals, which can still be raised, and feeding the harvest shrimp is also a good choice. As for the beautiful bony coral, novices should give up, the conditions for entering the pit are too high, so I won't mention it for the time being.
How can you play with the sea tank without the colorful saltwater fish?
Now it's time to talk about marine fish, which is also the focus of sea tank lovers. Here I have to mention a suggestion, that is, to establish the concept of quarantine tanks. Marine fish species are very different from freshwater ornamental fish, so they are more complex. When catching marine fish, people usually use some chemical means, and then go through a long period of transportation, as well as various quarantines, it can be said that the marine fish that can be seen in the aquarium, no matter how small, are tough guys.
So, is it suitable for you to raise beautiful marine fish? Sorry, before the marine fish become our pets, let's stay in the quarantine tank for a few days, which is also a responsible attitude for both parties.
If the saltwater fish carry diseases and parasites, then the hard-working tank of water, even the original fish and corals, may suffer. What if there is no quarantine tank? It depends on the ability to maintain water quality, and good water with stable water quality indicators can increase the resistance of fish, which is universal in the biological world.
Let's talk about the types of marine fish, there are many and they are also very particular. Like spiny dolphins, dogheads, and lionfish, these marine fish are ferocious and feed on small fish. There are also seaweed eaters, and butterfly fish, which eat coral, oh my...... You have to be careful, if you buy the wrong coral, you should cry and faint with the corals you have worked so hard to cultivate. It is also necessary to understand the habits of marine fish, such as the ferocious ones, and if they are kept together, it will be a life-and-death struggle.
My suggestion is to start with the simplest, still inspired by "Finding Nemo" - clownfish + anemone. Clownfish are beautiful and docile, and they can also live in symbiosis with corals and sea anemones. The physique is also relatively solid, and one thing to note is that if you raise a few at a time, it is recommended to let them into the tank together, so that they can adapt to the environment faster. As long as your fish are open to eat, then maintain good water quality and their health will not be too much of a problem.
Playing with the sea tank, equipment is our pain point!
Finally, let's talk about the equipment for playing sea cylinders. Let's talk about the fish tank first, the filtration of the sea tank generally chooses the bottom filter or the back filter, but there is a prerequisite, that is, there is a large enough filtration space. Because the sea tank needs more filter media, so that nitrifying bacteria can play a better role, which is also the key to the health of the water quality of the sea tank. Also, don't try to raise marine fish in the original freshwater fish tank, it's better to have it professionally modified.
Others, is some sand options, shell sand, coral sand can be, spread 3 to 5 cm thick. In addition, the effect of light on corals is quite large. If possible, you can choose halogen lamps and full-spectrum lamps for seawater. Note: The violet spectrum is not violet light, which is not visible to the naked eye, but is very useful for corals.
As for some equipment such as heaters, wave pumps, and detection devices, I won't talk about them here. After all, after the key steps are in place, playing with the sea tank is already half the battle.
summary
Strictly speaking, there are three main ways to play the sea tank: FOT (pure fish tank), main SPS (bony coral) tank and main LPS (soft coral) tank. I didn't go into detail about the specific gameplay in this article, but I just talked about some things that seem to be theoretical, but it will definitely help you establish a concept of playing sea tank, at least it can provide some food for thought!
As for many aquarists asking me what brand of equipment to buy, I really can't answer this question, after all, it involves products, there is a suspicion of advertising, please forgive me.
Finally, I would like to remind everyone that the sea tank is indeed very shocking, but you must be rational about playing sea tank. Maybe you're thinking about owning a small piece of sea after you have 2 clownfish and a few anemones...... However, the hands that can't be controlled are like the fish you can't raise, you can't stop at all!
In short, you need to be cautious when you "go to the sea"! Although it is not difficult to play with the sea tank, this pit is a bit deep!
Thank you for reading!The above personal opinions, if there is anything inappropriate, please criticize and correct the aquarists!
