Freshwater vs Saltwater Aquariums: Which One is Right for You?

Deciding to set up a fish aquarium can be a fun, rewarding experience. Choosing which type of setup is best can be a bit intimidating. With some research and our advice on which fish tank is right for you, freshwater or saltwater, you can be on your way to enjoying your beautiful new aquarium soon.

It is important to consider how much time and money you are willing to invest in your new aquarium.
Freshwater fish are usually far cheaper than saltwater fish. On the other hand, saltwater fish come in a more exotic array of colors and body shapes. Setups for both types of aquariums can range from very simple to very complex; although even a beginner saltwater tank can take a lot of your time and a significant amount of money.. No matter which type of setup you choose, you will need a few basics such as lighting, substrate, a water filter, and a thermometer.

Maintenance for a freshwater tank will involve changing a portion of the water on a regular basis. 25% is the recommended amount to change, every two to three weeks. Maintenance for a saltwater tank will also involve regular water changes at a smaller volume of approximately 10% every two weeks. When replacing the water in a saltwater tank, the salt content and specific gravity will need to be checked to make sure it is still balanced. Mixing your own saltwater using salt and the necessary nutrients is an option, but there are also mixes available that already have it figured out for you; just follow the instructions.

In addition to bi-weekly water changes, you will also need to check the water temperature each day to ensure it is within the safe range for your fish. Checking that the filter is operating properly should be done daily as well as checking for evaporation. If evaporation is noticed, you should add water. Failing to do this could harm your fish because their environment will become unbalanced.

Weekly tests for ammonia and nitrate buildup will be required by your saltwater aquarium. Filters should be cleaned weekly, and any buildup of algae will need to be removed also.

When changing the filter in your saltwater aquarium, it is best not to do this during the same time you perform a partial water change, as it can upset the natural balance of the tank. Wait a few days before replacing the filter, or replace the filter a few days before the partial water change. It is a good idea to check the tank cover and light during this time as well, and remove any buildup of dirt, salt, or other deposits. Check your equipment for these types of buildup also.

As you can see, the time spent maintaining a saltwater aquarium can be significantly higher than the time needed to maintain a freshwater aquarium. The cost of maintaining a saltwater tank will be higher as well.
