Features of 50-Gallon Aquariums

Before buying your 50-gallon aquarium, there are some important considerations you need to factor into your decision. This will ensure that you pick the right choice and get the most of your tank.

  • Material: Fish tanks are normally made from either two substances: glass or acrylic. The benefit of glass is that they are less likely to have discoloration over time and they are less likely to scratch. Acrylic aquariums are much lighter in weight, they have better visual clarity, and they are much sturdier.
  • Filtration systems: Some tanks come with a built-in filtration system while others do not. Built-in filtration systems usually come with smaller sized tanks, but they can still be found with some larger sized ones. The benefit of a built-in filtration system is that you won’t need to buy one separately. However, sometimes the built-in filters that come with tanks are of lower quality.
  • Shape: The most common tank shape among fish tank owners is a rectangular box-shaped tank. However, some other shapes include cubes, cylinders, and hexagons. The benefit of rectangular box-shaped tanks is that they are more compatible with other aquarium products like decorations, filters, and UV lights. The benefit of the other tank shapes is that they have an appealing visual edge to them that sets them apart from other tanks aesthetically.

Types of 50-Gallon Aquariums

  • Community tank: Community tanks are the most popular tanks in larger sized aquariums. They consist of several different types of species all living together in one tank. These tanks usually hold a couple of plants. It is important that you choose fish that are able to swim peacefully beside other fish and coexist with one another.
  • Species-only tank: A species-only tank is perfect for fish tank owners who are mostly interested in one type of fish. With this type of tank, there is only one species living in the water. This can be due to the owner only liking that one type of species, or that species can be aggressive and not able to coexist alongside other types of species.
  • Planted aquarium: In this type of aquarium, plants are the main focus. Although there might be some type of fish being kept in the tank, the main focal point is the plants. A planted aquarium is meant to resemble a real-life aquatic environment that replicates underwater schemes.
  • Paludarium tank: This type of tank holds 50% aquatic life and 50% aquatic plants. This type of tank also resembles a realistic underwater environment. Different variations of plants and aquatic life vary among fish tank owners and their preferences. There is usually less diversity among species than a community tank would have. However, with paludarium tanks, you often see different creatures such as snails, reptiles, and turtles.

How to Maintain A 50-Gallon Aquarium

With a larger sized aquarium, a powerful filtration system is absolutely necessary. Choosing a filter with a high flow rate is going to make sure there is an active current that reaches all of the water in your tank. If your filter is not powerful enough, it will not as good of a job at cleaning the tank.

A 50-gallon aquarium will actually need to be cleaned less frequently than a smaller tank would need to be cleaned. This is because in a larger tank, the bacteria and toxins have a larger space to disperse and will not be as harmful to the water.

On average, it is recommended that the tank water is changed approximately every two weeks. The amount of water that is changed out should be around 15%, although some fish tank owners change out a larger amount.

The number of fish also depends on how often you clean your aquarium. The larger the amount of fish that are being kept in the tank, the more often it will need to be cleaned. This is due to the increased amount of waste being produced by the fish. Also, it will depend on what type of fish you have. Some fish produce more waste than others. For example, betta fish usually produce less waste while goldfish tend to produce more waste.

It is very important to make sure your tank’s water is at a proper temperature. Maintaining the proper temperature of your tank is necessary in order to keep your aquatic life and plants healthy. This can be accomplished by purchasing an aquarium thermometer that monitors the temperature of your tank and alerts you when it is at a dangerous temperature.
