preview

Skip to ContentAt first glance, it could be easy to tell the differences between a saltwater aquarium and a freshwater aquarium. Perhaps you are suddenly urged to get an aquarium but unsure which one would be best for you. What are all the differences between a saltwater and a freshwater aquarium?Saltwater aquariums are more costly, are more high maintenance, and have bigger space requirements. They offer a wide range of fish and other organisms. Freshwater aquariums have fewer fish choices, but they are less maintenance, and more affordable. Freshwater fish are hardier than saltwater fish.Choosing between these two types of aquariums could be challenging if you’re not educated on the subject. Continue reading as we discuss:Just as you need adequate space around you, an aquarium also needs sufficient space. The space is mainly used for easy:Make sure to select a big enough area that won’t block any accessories you need to access, such as the back of the aquarium for filtration and the top for lighting and water changes.Note: This post may contain affiliate links which will take you to online retailers that sell products and services.

The larger space you have for your aquarium, the better it is for the fish.Additionally, if you have a larger aquarium, whether it is saltwater or not, it will dilute toxins much better, so if you make mistakes, it won’t have a significant impact on your fish. Larger-sized aquariums will also cycle much faster, resulting in a shorter stress period for your fish.One of the most difficult responsibilities that come with aquariums is the water changes. Although this type of work can be both challenging and time-consuming, it is an essential part of maintaining a healthy aquarium.Let’s look at saltwater and freshwater aquariums, and the maintenance needs of both:Saltwater aquariums will initially require much more work, as you must mix the water perfectly beforehand. Usually, it is also agreed that saltwater aquariums are more challenging to maintain.Saltwater and water parameters, such as salinity and pH, are generally stable since there is so much water in the ocean.This means that rapid changes in water parameters are not possible. Therefore, marine life has evolved so that it can only survive in water conditions that are kept constant.So, when you have a saltwater aquarium, you will need to spend most of your time stopping the water parameters from fluctuating.The salt will take time to dissolve in the water, and you will need to check the salinity levels, which could take some time.You do have a choice to make this step of the water changing much easier, by mixing the saltwater beforehand. You can also choose to purchase pre-mixed saltwater from an aquarium supply store.When it comes to maintaining your freshwater aquarium, it is much more straightforward. The freshwater requires no sitting or mixing.However, if you use tap water to fill a freshwater aquarium, such as water from a hose or kitchen sink, treat it to eliminate toxic chemicals that could put the freshwater fish and plants in danger.The type of aquarium you choose will significantly influence the type of equipment you need. Of course, you can purchase whole sets on Amazon, like this one that may require less additional equipment with both types of aquariums.Let’s take a look at the equipment requirements for saltwater and freshwater aquariums (all the items listed are links to the specific products on Amazon; ones that I find are great value for the quality they offer):Having an aquarium will cost hundreds of dollars, no matter which type you choose. It might help to save before starting this expensive hobby if you’re on a budget.Let’s look at the costs you can expect from a saltwater and freshwater aquarium:Saltwater aquariums usually cost between $1,000 and $2,000 for the livestock and tank. Depending on the size of the desired tank, it could exceed this amount.As seen above, saltwater aquariums require more equipment to keep the tank up and running, and the equipment is more costly than what is needed for a freshwater tank.Usually, saltwater aquarium tanks are bigger than freshwater tanks, as they need more equipment and space for needed decorations, fish, and extras.Setting up a saltwater aquarium could be as cheap or expensive as you want because the bigger your tank, the more expensive the needed equipment.When it comes to a freshwater aquarium, there will be less equipment, the fish tend to be more affordable, and the equipment is cheaper than saltwater aquarium equipment.Potential buyers often see the prices of special package deals and assume they can start freshwater tanks for as little as $50. However, this is not the case, and realistically it would cost around $150 to $200 to purchase a twenty-gallon aquarium with beginner equipment.If this investment seems too expensive for your budget, it may be wise to save and invest in a freshwater aquarium once you become more experienced in looking after it.Both saltwater and freshwater tanks could add a touch of color and aesthetic value to your home. Let’s look more closely:The biggest attraction to saltwater aquariums is usually the wide variety of fish and other marine life that can be kept in one. There are many unusual creatures to choose from, such as:Create some aquascapes in your home from different color lights giving a room a calm, relaxing, and beautiful aesthetic!Although some varieties of freshwater fish have appearances that are similar to marine fish, they tend to be less vibrant and colorful.At some point, you may want to expand your horizons with a colorful coral reef, which is not possible to achieve with a freshwater aquarium.Furthermore, you can install lights on your freshwater aquarium and achieve a beautiful and expensive aesthetic to your home, but it won’t have the same vibrancy of a saltwater tank.Suppose you have a freshwater aquarium and want to convert it into a saltwater one or vice versa. Luckily, the tanks are not specially designed for one or the other, so don’t run out for another tank just yet!As long as your tank holds water without leaking, whether it’s acrylic or glass will not make a difference.However, the most significant difference is the aquarium’s size. For the most part, the larger your aquarium is for saltwater, the better it will work.If you have a smaller aquarium, such as 10 gallons or less, if problems or mistakes arise, things could become life-threatening to your fish. Including serious issues such as high ammonia during cycling, which must be fixed immediately.Even though you can convert your freshwater tank into a saltwater one and vice versa, you need to keep in mind that you can’t place as many saltwater fish in a particular-sized tank as you would be able to place in a freshwater one.TIP: The general rule for the number of fish in a freshwater tank is about one adult fish per gallon of water. The general rule in a saltwater tank is one adult fish for every 5 gallons of water.Choosing the ideal aquarium might be difficult, especially keeping all the things above in mind. However, you can narrow your choice down by looking at the pros of cons of each and deciding which one would suit your wants and needs.Take a look at our complete pros and cons list of saltwater and freshwater aquariums:Having a saltwater aquarium in your home has many benefits, and guests will turn their heads at this beautiful sight.

Mistakes are also more likely to occur and put your fish’s lives in danger.Saltwater aquariums have to be larger than freshwater ones, as saltwater has 20% less dissolved oxygen in the water.You will need a much larger one to keep the same amount of fish in a saltwater aquarium.In the natural marine environment, the water parameters stay relatively constant. Therefore, you have to ensure the conditions in your tank stay constant, as sudden changes could kill the fish.Before you decide on a saltwater aquarium, you may need to take note of all the good things a freshwater aquarium has to offer:Most people prefer to start their journey with a humble freshwater aquarium as their first tank. This is because freshwater aquariums offer low and high versatility requirements.

The fish are cheaper, and the tanks need much less equipment, which helps to keep it fun and affordable!The maintenance requirements for freshwater aquariums are much easier and simpler.
