What Are The Benefits Of A 100 Gallon Tank?

A 100 gallon fish tank is a sizable investment both in terms of money and time, but it can be a worthwhile addition to your home. Not only will it provide you with a beautiful and relaxing aquarium, but it will also offer a number of benefits for your fish.

First, a larger tank will allow your fish to have more space to swim and explore. This can help to reduce stress levels and improve their overall health. In addition, a larger tank will also provide more stability in water conditions, making it easier to maintain ideal water quality.

Finally, a 100-gallon fish tank will give you the opportunity to create a more elaborate and realistic underwater environment, which can be both visually stunning and beneficial for your fish. With careful planning and attention to detail, a 100-gallon fish tank can be a rewarding addition to any home.

What To Consider When Choosing A 100 Gallon Fish Tank

Here are some things to consider when shopping for the best 100 gallon fish tank. 


When choosing a 100 gallon fish tank, one of the most important factors to consider is the size. The dimensions of the tank will determine how many fish you can keep, and how easily they will be able to move around.

 If you have a small home or limited space in your office, you may want to consider a smaller tank. However, if you have a large home or plenty of space to spare, a larger tank may be more suitable.


When shopping for a 100-gallon fish tank, one of the most important factors to consider is the shape. Some common shapes include rectangular, square, and hexagonal. Each has its own benefits and drawbacks. For example, rectangular tanks typically offer more swimming space for fish, while square tanks often take up less floor space.

Hexagonal tanks are a good compromise between the two, offering a decent amount of swimming space while still being relatively compact. Of course, the shape of the tank is ultimately up to you and should be based on your personal preferences.


When choosing a 100-gallon fish tank, one of the first things you need to take into account is the material. Glass is a popular choice for fish tanks, as it is clear and durable. However, it is also heavier than other materials, such as acrylic, and can be more difficult to clean. Acrylic is another popular choice for fish tanks, as it is lighter weight and shatter-resistant.

However, it can scratch more easily than glass and may yellow over time. As a result, it is important to carefully consider the pros and cons of each material before making a decision. 


Not only do you need to think about the size and shape of the tank, but you also need to consider the accessories that come with it. For example, you’ll need to choose a filter that is designed for a 100-gallon fish tank. You’ll also need to decide whether you want an air pump or not. And finally, you’ll need to select the appropriate lighting for your tank.


First and foremost, you need to consider the type of fish you want to keep. Some fish, such as goldfish, require a lot of space to swim and thrive, while others, like bettas, do better in smaller tanks.

 You also need to think about the level of care required for the fish you’re interested in. Some fish are very low maintenance and can be kept in a basic setup, while others require a more complex setup with live plants and other decorations.


Price is an important consideration when choosing a 100-gallon fish tank. You want to find something that fits within your budget but also offers the features and quality you need. It’s important to remember that you’ll need to factor in the cost of accessories, such as filters, heaters, and lighting. In addition, you’ll need to budget for regular maintenance, such as changing the water and cleaning the tank.

How Much Does A 100 Gallon Fish Tank Cost?

A 100-gallon fish tank can cost anywhere from $200 to $5,000. The price will depend on the quality of the materials used, the size of the tank, and any extra features that are included. For example, a tank made with high-quality glass will be more expensive than one made with acrylic.

 Likewise, a tank that is larger in size or has special filtration systems will also be more expensive. With that being said, it is possible to find a 100-gallon fish tank for a reasonable price if you are willing to shop around. With a little bit of research, you can find a tank that fits both your budget and your needs.

How To Setup A 100 Gallon Fish Tank

Here’s some tips on how to set up the best 100-gallon fish tank.

Choose the Right Spot in Your Home for Your Fish Tank

Before you bring your new fish home, you’ll need to choose the perfect spot for their tank. First, consider the amount of natural light in the room and whether or not you’ll need to supplement it with a grow light. Next, think about the traffic in the room. A busy household may not be the best place for a fish tank as sudden noises can startle the fish. 

Get a Tank That Is Big Enough to Fit All of Your Fish

Before you start shopping for a fish tank, it’s important to have a good idea of how many fish you want to keep. A 100-gallon tank is a good size for a medium-sized freshwater aquarium. It’s also important to consider the type of fish you want to keep.

Some fish, like goldfish and bettas, prefer to live in smaller tanks, while others, like angels and guppies, need more room to swim.

Purchase a Filter and Heater for Your Tank

You will need to purchase a filter and heater for your tank. These two items are essential for keeping your fish healthy and happy. 

Decorate Your Tank With Plants and Rocks

Once you’ve found the perfect spot, it’s time to start thinking about decoration. One way to add interest to your tank is by incorporating live plants. Not only do they look great, but they also help to keep the water clean and provide hiding places for your fish. Rocks are another popular option, and they can be used to create caves and tunnels for your fish to explore. 

Add Water and Conditioner to the Tank

Before adding any fish to your tank, you’ll need to cycle the water to build up a colony of beneficial bacteria. This process can take anywhere from 2-8 weeks, so be patient! To get started, fill your tank with fresh water and add a dechlorinating conditioner to remove any harmful chemicals.

Then, you’ll need to add ammonia to the water. You can do this by adding a few drops of liquid ammonia or by placing a small piece of raw shrimp in the tank. Ammonia will help to jumpstart the bacteria colony. Once the ammonia levels have spiked and then dropped back down to zero, your tank is ready for fish!

How To Maintain A 100 Gallon Aquarium

Here are some tips on how to maintain a 100-gallon aquarium. 

Perform a Water Change Every Week

One of the most important things you can do to maintain a 100-gallon aquarium is to perform a water change every week. This will help to remove any build-up of toxins and waste, and it will also replenish the water with essential nutrients. When performing a water change, be sure to use an aquarium vacuum cleaner to remove any debris from the gravel.

Then, use a siphon hose to remove about 25% of the water from the tank. Finally, use a water pitcher or bucket to add fresh water to the tank. Be sure to use treated tap water that has been allowed to sit for at least 24 hours before adding it to the tank. 

Test the Water Parameters Regularly and Make Adjustments as Necessary

One of the most important things to do is to test the water parameters regularly and make adjustments as necessary. Ammonia, nitrites, and nitrates should all be kept at safe levels in order to prevent harm to your fish. Additionally, the pH of the water should be monitored and kept within a range that is comfortable for your fish.

Feed Your Fish Only What They Can Consume in a Few Minutes

One of the most important thing to remember is to feed your fish only what they can consume in a few minutes. Overfeeding not only creates water pollution but can also cause health problems for your fish. A good rule of thumb is to offer them no more than they can eat in three minutes.

Remove Any Uneaten Food After 5 Minutes

 A general rule of thumb is to remove any uneaten food after 5 minutes. This will help to keep the water quality high and prevent the build-up of harmful toxins. It’s also a good idea to offer a variety of different foods to ensure that your fish are getting all the nutrients they need.

Add Fresh Plants to the Tank Every Few Weeks

Fresh plants help to oxygenate the water, which is essential for fish respiration. In addition, plants help to remove nitrates from the water, keeping levels low and reducing the risk of algae growth.
