How to Maintain A Saltwater Fish Tank? It is fairly popular to have aquariums set up as a piece of decor in one’s home. This not only contributes to the beauty of our space, but it also gives it life. If you think about it, this modest piece of decor can be divided into several sorts based on the differences in setup and composition. In this article, we will share some useful tips on how to maintain a saltwater fish tank.
How to Maintain A Saltwater Fish Tank
The term “Marine Aquarium” refers to a type of aquarium that must be filled with marine plants and animals. This can be further broken into the types listed below:
- Fish Only (FO)
- Fish Only with Live Rock (FOWLR) and
- Reef Aquaria
Marine fish husbandry differs from the other varieties in that it takes more expertise and research. A thorough understanding of the composition of water, its chemical qualities, and the adaptation of marine aquarium residents is essential.
To begin, let’s go over the first stage in installing a ‘Marine Aquarium System,’ which comprises all of the primary components required for a marine aquarium.
A Marine Aquarium’s Major Components
The first requirement for installing a Marine Aquarium is a thorough understanding of all of its primary components. Marine Aquariums often range in size from less than 80 liters to over 1200 liters. The following are the major components of a Marine Aquarium:
- A glass- or acrylic-encased aquarium
- Aquarium Heater and Refrigeration Devices o Filtration Equipment o Proper Lighting o Aquarium Heater and Refrigeration Devices
The aquarium should be made of glass or acrylic as much as possible. Glass is commonly utilized due to its tensile strength, transparency, and low cost. Glass also provides the unique ability to evenly distribute total pressure throughout the aquarium.
Acrylic, on the other hand, can be used as a substitute for glass because it is lightweight and easily moldable into a variety of forms and sizes. It is also scratch-resistant and provides significantly greater electric insulation, despite its somewhat higher price.
A marine aquarium’s filtration system is far more complex than that of conventional freshwater aquariums, and it comprises physical, chemical, and biological filtration.
Wet and Dry Filters, as well as Protein Skimmers, are the most widely used filtration equipment. A Protein Skimmer is a device that removes organic substances from the water before they’re broken down further into nitrogenous wastes.
Protein skimming is an important filtering procedure because it is the only method of filtration that physically removes organic components before they degrade, increasing the water’s properties.
A Refugium or a Sump can be found in some marine aquariums. A refugium is a small container, or more commonly a small aquarium, that sits beneath a marine aquarium and is fed by a water pump. A sump, on the other hand, is made up of several chambers, each with its own filtration material.
Because lights play such an important part in marine aquariums, appropriate illumination is critical. Although it is recommended to set up a cycle lighting arrangement to excite the day and night, this differs depending on the aquarium’s residents. Intense light is not required for a conventional ‘Fish Only’ kind.
In the case of aquariums with invertebrates, however, a bright light is desirable. Fluorescent, VHO Fluorescent with very high intensity, Compact Fluorescent, LED, and Metal Halide is the most often used lights.
Although there are many variants in terms of light sources, each technology has its own set of benefits and drawbacks. Wattage and color temperature are the two most significant elements to consider when choosing a lighting system. Depending on the type of lighting utilized, the wattage of the lights might range from tens to several hundred.
On the other hand, color temperature refers to the color of light emitted by the lighting system. Growing plants in marine aquariums require a color temperature of >5000K. The colors of fish and corals are affected by a 10,000K lighting system, which emits bluish-white radiation.
A considerably greater spectrum, such as 14,000K and 20,000K, provides deep blue radiation akin to that found underwater and creates a similar environment.
The temperature in a Marine Aquarium should be kept between 24 and 28 degrees Celsius, which is similar to the natural climate in which the marine residents live.
An ‘Aquarium Heater’ is used when the aquarium temperature falls below the ideal setting. If the temperature in the aquarium rises over the acceptable level, a cooling device known as a ‘Chiller’ is employed to lower the temperature.
Step 1: Setting Up a Marine Aquarium
The second significant phase is the setup process, which begins once you have all of the necessary components for a Marine Fish Tank. It’s a lengthy procedure that could take anywhere from 4 to 8 weeks before you can add any marine life to the setup. The following are the major steps in the setup procedure:
- Choosing the aquarium size and location o Gathering the necessary aquarium equipment o Putting the aquarium together with all of the necessary equipment
- Filling the aquarium with previously mixed saltwater o Curing the live rock o Adding the substrate o Thoroughly monitoring the water and allowing the tank to cycle
- Incorporating marine fish
So let’s go over all of the important points one by one.
The size and location of the aquarium are determined by the sort of marine fish you want to keep. This is due to the fact that the size and growth of marine fish can range from an inch to 12 or 18 inches.
Smaller tanks should always be avoided because they necessitate more frequent water testing and maintenance. The ideal location for your marine system is somewhere where external sources of light and temperature, such as windows or heater vents, have little impact on the aquarium’s light and temperature. Last but not least, the stand must be capable of supporting the aquarium’s complete weight.
Essential aquarium equipment: Before beginning the process of building up a marine aquarium, make a list of all the necessary equipment and organize it so you don’t forget anything. The type of filtration is the first thing you must consider.
In this scenario, a combination of live rock as a biological filter and a protein skimmer as a mechanical and chemical filtration approach is ideal. Arrange the live rock, sand, and a power strip in the appropriate places.
The ideal choice is live sand or aragonite-based sand, especially from the Caribbean. Crushed coral is also a good option, but avoid using sandbox or playground sand because it is hazardous to your marine life.
Set up your aquarium: When cleaning the tank, avoid using soap or detergents because the soap residues are toxic to marine animals. Only use water to clean it, then fill it with new water to test for smoke and leaks, if any exist.
Once the test is completed, drain the water and go to the next step, which is to create a background. It’s best to paint the background because there’s no way for salt creep to get between the background and the glass.
The painting should be done on the backside’s outer wall rather than the interior wall. For marine tanks, a black background is good since it highlights the color of the fish.
Alternatively, deep blue might be used to create a sense of sea depth. Install the heater, filter, and protein skimmer after the tank has been left for a day to let the paint dry.
Remember to use a drip loop on all power lines and double-check the electrical routes in the aquarium.
Steps 2: Marine Aquarium Setup
Unless you’re building up a reef tank, you can use most of the regularly available saltwater combinations. Fill a 5-gallon bucket halfway with water and remove the chlorine and chloramine with Aquarium additives and medicines.
Then, while constantly stirring, gently add the salt mixture to the room-temperature water. Test the salt mixture with a hydrometer or refractometer once you’re confident it’s thoroughly dissolved.
The water is ready to be put in your aquarium after the specific gravity hits between 1.021 and 1.024. Turn the aquarium on for at least a day or two to allow the water to circulate.
Curing the live rock: Live rock is an important feature of a Marine Aquarium, despite its high cost. This is due to the fact that living rock is thought to be the greatest biological filtering method.
The curing time might last anywhere from a week to two months, depending on the shape of the rock. Place the live rock in the center of the aquarium after draining some water and aiming the powerheads at the rocks.
Brush the rocks every few days, but remember to switch off the power in the tank. To scrape and remove the dead organisms in the rock, use new rubber kitchen gloves or a brush with plastic bristles.
Fill the tank with previously mixed saltwater after siphoning the disposals. Remember to include a powerhead and a heater in the mixing container to guarantee consistent mixing and to test the tank on a regular basis to check that it is cycling.
When the tank stops smelling terrible, that’s a better indicator that the live rock is cured. Make sure the tank water is clear of ammonia and nitrite by testing it at regular intervals.
Adding substrate: After the live rock has finished curing, you must prepare your aquarium for the substrate layer. To do so, first, remove some water from the aquarium to make room for the sand, and then switch off the tank’s power.
Pre-mix roughly 2 gallons of seawater in a large bucket, like a 5-gallon bucket. Continue to swirl the sand into the pre-mixed seawater.
Dust and undesired particles will come to the surface if you keep stirring, and you’ll have to gently drain them away. Drain some saltwater from the mixing bucket, and then slowly add the clean sand to the tank with a ladle or something similar.
If any sand particles get inside the live rock, you can blast them off with a powerhead. So, it appears that the procedure of setting up a marine tank has finally come to an end.
At this point, the only thing that can be done is to wait for the tank to settle. Continue to monitor the water parameters for a few more days without upsetting the tank too much.
Steps 3: Create a Marine Aquarium
Monitoring the tank: Once the aquarium is complete with all of the necessary components, it will require a few days of standing time to settle down.
The most crucial responsibility during this period is to regularly check all of the delicate factors in order to maintain an ideal environment for the marine fishes. The monitoring entails:
- Keeping an eye on the aquarium’s water temperature
- Checking the aquarium water’s specific gravity o Checking the aquarium water’s pH balance
- Checking the ammonia level in the aquarium water o Checking the nitrite level in the aquarium water o Checking the nitrate level in the aquarium water
- Inspecting the aquarium’s carbonate hardness level
All of the parameters listed above should be within the appropriate range. Any of the following elements that are out of balance can pose a harm to marine life. As a result, it is recommended that this monitoring process be carried out with extreme caution.
If an imbalance is discovered, it must be corrected and brought back to normal before adding marine fish.
The aquarium’s temperature should be between 75°F and 80°F (24°C and 27°C), and the specific gravity should be between 1.020 and 1.024. Furthermore, the aquarium water pH should be between 8.0 and 8.4.
It’s important to note that the ammonia and nitrite levels in aquarium water should be zero. To put it another way, the aquarium water must be free of ammonia and nitrite.
However, the nitrate concentration of the water should be less than 20ppm, especially for invertebrates, and the carbonate hardness range should be between 7 and 10dKH.
The water we drink on a regular basis is generally high in phosphates, which must be avoided. The presence of phosphate in aquarium water encourages the growth of some unwanted algae.
Snails, shrimps, starfish, and other invertebrates may be harmed by even a small amount of copper in the aquarium, while fish are unaffected. Keeping water in motion is one of the most critical aspects of improving water quality.
Moving water is ideal for gaseous exchange, keeping the water oxygenated and hence beneficial to the health of the fish. Using a powerhead is the greatest technique to keep the aquarium water moving.
Pumps also have a vital role in removing excess carbon dioxide from the water, which could otherwise result in a low pH. It is recommended that salt, calcium, alkalinity, and temperature levels remain constant. Allow the aquarium water to stand for a period of time so that the water chemistry can stabilize, which is critical.
A basic rundown of water chemistry:
– Temperature Range: 75°F – 80°F (24°C – 27°C)
– Specific Gravity Range: 1.020 to 1.024
– pH Range: 8.0 to 8.4
– Ammonia Level: 0
– Nitrite Level: 0
– Phosphate Level: 0
– Copper Level: 0
– Nitrate Range: 20ppm or less, especially for the invertebrates
– Carbonate Hardness Range: 7 – 10dKH
Step 4: Set-up the Marine Aquarium
Adding Marine Fishes: Once the water chemistry has settled and the tank has been completely cycled and ready, it is the ideal time to introduce marine life to your Marine Aquarium System.
Marine species include anemones and other marine invertebrates in addition to fish. Maintaining saltwater fish necessitates a thorough awareness of their behavior, as well as additional skill sets and expertise. This is due to the fact that marine fishes are physiologically different and less adaptive than freshwater ones.
Everything you need is a comfortable environment and some unique treatments and conditions; the fish don’t require any further attention. In comparison to freshwater aquariums, a saltwater or marine aquarium may house a broader variety of stunning fish.
Damsels, Lionfish, Clownfish, Triggerfish, Blennies, Butterflyfish, and marine Angelfish are some of the most popular saltwater fish. Certain species of marine fish, such as clownfish, wrasses, anthias, and marine betta, add a splash of color to your aquarium.
Once your marine aquarium system is up and running, it’s best to start with the more popular, hardier marine fishes, and Damsels are ideal for this. Damsels, in comparison to other popular marine species, are significantly more durable and less expensive.
However, keep in mind that Damsels are aggressive by nature and hence are not friendly with many other marine species. Keep your marine aquarium on some of the few tough marine fishes for another six months, and don’t forget to keep a check on the aquarium water’s conditions.
After around six months, try adding some of the hardy invertebrates if everything is doing well and nicely balanced. Soft corals, algae, shrimp, anemones, starfish, and urchins are some of the resilient invertebrates you can start with.
Other common animals, such as worms and sponges, can be added to your marine aquarium. After one to two years of successful addition and care of these invertebrates, you can start thinking about the more sensitive invertebrates like stony corals and clams.
You can even accommodate larger invertebrates like jellyfish and octopuses in an advanced stage of your marine aquarium. So, as you would have guessed, a marine aquarium can house a considerably larger variety of animals than a freshwater aquarium.
Last but not least, for the proper growth of marine fishes, a healthy and roomy atmosphere is essential. Never overstock your aquarium, which is a common mistake made by newcomers, in order to offer a healthy habitat.
Another typical mistake to avoid is overfeeding the fish, which can result in poor water quality and even illness, leading to the death of your aquarium fish. It’s best to feed your marine fish in little amounts so that everything gets eaten up and the water doesn’t get too dirty.
Aside from the technical aspects, one of the most important tasks is to inspect your aquarium fish and invertebrates for health and movement. If you notice any signs of illness, examine your water conditions, look for disease symptoms, and then seek help from your marine aquarium merchant or online literature. We hope this article on how to maintain a saltwater fish tank was worth reading.
