Aquariums are not designed only to be used as either a freshwater tank or a saltwater tank; most aquariums can be used for either. The glass or acrylic material that makes up the structure of the aquarium certainly applies to both freshwater and saltwater aquarium tanks. The silicone adhesive that is used in construction is also applicable to both freshwater and saltwater aquariums.

The one main difference between freshwater and saltwater tanks is that freshwater tanks tend to be considerably smaller than their saltwater counterparts. While a 5-gallon freshwater tank can theoretically be transformed into a saltwater tank, small saltwater tanks are often harder to work with, which is why many experienced saltwater aquarists suggest that you use no smaller than a 55-gallon tank for your saltwater aquarium.

Regarding the filtration of your aquarium, filtration is a little more involved when it comes to saltwater aquariums, since biological filtration is an especially critical component in a saltwater aquarium. Freshwater aquarium owners can choose to use a biowheel and box that hangs on the outside of the tank or in a corner of the tank for filtration needs, but a saltwater tank usually needs more filtration than that which these types of filters can provide. While undergravel filter (UGF) set-ups can be used in saltwater aquariums, they can contribute to unwanted nitrate problems in later years, which is why many saltwater aquarium owners prefer wet-dry trickle and canister type filters that have bio-media chambers.

There is no set choice for a filter to be used in a saltwater aquarium; your best bet is to research the various filtration methods and set-ups, than choose the one that you feel will work best for your aquarium.  You can usually help to narrow your decision by deciding whether you will have a fish-only aquarium or a reef tank system, though filters that are used for reef tank systems can also be used for fish-only aquariums, so you can save money and hassle by purchasing filters that will work with reef tank systems even if you only initially plan on having fish in your saltwater aquarium.

Regarding pumps and powerheads, most freshwater pumps can work well in saltwater aquariums, provided that they are rated as safe to use in saltwater. The main difference between freshwater and saltwater aquariums is that saltwater aquariums use more pumps and powerheads to obtain greater movement and circulation in the water. This can be especially beneficial to the health of corals.

Many freshwater aquarium owners use large-sized gravel or rock material to provide the biological filter base. However, this does not work well in a saltwater tank, as the substrate that is used in saltwater tanks should have high natural levels of calcium content that originates in the ocean. One solution that you can use in both freshwater and saltwater aquariums is ONEdersave’s EcoBio-Block® aquarium products. Their EcoBio-Stone™ L works especially well in larger saltwater tanks, as it is made to be used in 16 to 100 gallons of water.

The lighting used for freshwater tanks can work with fish-only saltwater tanks, though the light hood may not stand up well to the corrosive effects of saltwater, plus it will not hold MH, PC, or VHO lighting.  You certainly need to change the lighting if you plan on having a reef system. It is important that you carefully research exactly what you need for your aquarium before heading out to your local fish store so that you don’t buy unnecessary or inadequate equipment.

You will definitely need to change the decorations in your tank if you plan to convert from freshwater to saltwater, as most saltwater fish are grazers, and if you leave decorations that are made of plastic, your saltwater fish could have their digestive tracks shut down from eating such items. You should place either live rock or non-living or synthetic decorative rocks and corals in your saltwater aquarium.

The heater for your freshwater tank will likely suffice for your saltwater tank, provided that it is safe to use in saltwater tanks. You will need to use a different test kit, however, since the chemicals used in freshwater test kits are entirely different from those found in saltwater test kits.

In conclusion, some equipment from your freshwater aquarium will work well with your new saltwater aquarium, but some equipment will have to be replaced. By doing some careful research online and in saltwater aquarium books, along with the information in this article, you should be able to transform your freshwater aquarium into a saltwater aquarium quickly and at relatively little cost.

Saltwater Aquarium with Nemo

For many of us, having a saltwater aquarium would be like having a dream come true. However, we have been either scared away from owning what we would really like to have by some of the things we have read about having this type of tank, or heard from others about the woes of keeping saltwater fish. The beginner’s saltwater aquarium need not be a scary proposition!

What will be needed for the beginner’s saltwater aquarium? You need the aquarium itself, any kind of decorations you want in the aquarium and the right kind of filtration for a salt-water tank. This filtration may or may not include protein skimming. You will need the proper type of lighting apparatus and intensity that is not only suitable for marine fish, but also the type that will fit the tank you have selected.

The size of the tank that is chosen for a beginner saltwater aquarium can make quite a difference in the general health and well-being of the fish that live inside. It is important to remember that a larger tank is actually better for someone who is just starting out. One reason for this is that it has been proven that you cannot place as many fish in an aquarium prepared for saltwater fish.

The tank densities of each aquarium will of course vary, depending on the amount of salt and other substances in the water and the type of filter that is used to keep the water clean and clear. The best kind of filter for a beginner’s saltwater aquarium is one that uses biological, chemical, and mechanical filters together as a system.

It is easiest of all to start out with an aquarium that is going to be a marine-fish only tank. With just fish, you do not need to make the decision on whether you are going to keep live rock in your tank, or turn your tank into a small coral reef system. Crabs, corals, and sea anemones all require a different level of care. Marine fish alone can be relatively easy for a hobbyist to raise and keep healthy.

In order to keep marine fish in a saltwater aquarium, you are going to have to mix in some aquarium salt when you first set your tank up. With the use of an instrument called a hydrometer, it is easy to measure the water content in an aquarium to see if it has too much or too little salt.

What it is necessary to remember is that though the care can be very similar for both marine and freshwater fish, the requirements to keep them healthy can be quite different.  One thing remains the same, however, and that is the need for a bacteria culture in the saltwater tank as well as the freshwater.

These friendly bacteria can allow you to add a few more fish than your saltwater aquarium would be normally be able to handle without going into waste overload. The bacteria can also help you to keep the water quality in your tank clean and clear by constantly growing, multiplying and sending out new beneficial bacteria every thirty minutes that keeps the mulm from growing and seemingly multiplying out of control. Where can you get a salt-water tank accessory that will do all this for you and your aquarium?

You can get just what you need from the family of EcoBio-Block aquarium products. Not many products can do all of this, and last for 2 years as well! EcoBio-Block can, because their products are genuinely the best!
