Have a filtration system. Choose one that best suits your desired aquatic animals. Some filters cause water movement, which some fish do not like. For example tanks with shrimps should have little to no water flow.
Other species like to have water flowing since they are native to rough waters. This can be adjusted by acquiring filters with sponges to help minimize the water flow.
Larger fish also need a filter that is more efficient as they tend to produce more waste. Most filters that come in with a starter kit are decent enough to support the ecosystem of your tank.
LED lights are commonly used as lights for fish tanks. It is durable, effective, and has a low power consumption. Keep in mind that some species prefer dimmer places to thrive into.
When you have a community of fishes in your tank with different preferences, consider their needs. Make sure that in decorating your tank they have a place to hide when the fish do not prefer bright lights. Try lights that closely resembles natural sunlight or moonlight.
Lighting is also crucial in keeping your fish and plants healthy. For saltwater tanks, the inclusion of corals or having a reef tank will require different lighting.
Substrate Gravel and Sand
For freshwater tanks, if you are planning to keep aquatic plants in your aquarium, always have a good aquatic soil. Instructions vary as to how much soil you should put in your tank. In general, around 1 inch of aquatic soil is enough. You can alter it based on the layout you wish your tank will have.
Gravel and sand are also used as substrates, making your tank more pleasing to look at. Following the general rule of thumb, 1 inch of the substrate is enough. But as mentioned, alterations are acceptable, especially when dealing with aqua-scaping.
For saltwater tanks, use substrates to form the seabed. It is recommended to use coarse gravel as it is easier to maintain than sand. Sand is more prone to infestations of critter and bacteria than gravel.
When buying gravel, avoid dyed or painted ones. If you really want them colored then make sure it is nontoxic and won’t have a bad effect on the inhabitants of the tank.

Do this carefully so as to not clog the plumbing lines. For the gravel, wash it a few times. The point of this is to get rid of dust that might have accumulated on the substrate has accumulated display.
A need for a water heater will be dependent on the location of your tank. Water temperature is one of the many ignored factors in keeping aquariums. Most fish has temperature ranges.
The temperature of your tank affects the oxygen present in the water. Beneficial bacteria needs oxygen to break down ammonia which affects the overall health of your fish.
If the area where you will position your tank is quite warm you may not need a water heater. Consider all variables before setting up temperature for your tank.
Having plants can make your tank look more lively and natural. Plants can help in filtering the waste produced by your fish. When buying plants, keep in mind that there are aquatic pets that can eat your plants.
These fishes are herbivores. You can always ask other fish keepers or your local pet shop on what plants are best for the community of fish you are planning to have. Aquatic animals also love having a place to hide, stay into or play in.
Note: If you intend to keep a planted aquarium make sure that natural sunlight can reach your tank if not, you must provide lighting that can cater to your plants. Have a basic knowledge of plant care and maintenance. Taking care of your plants means a healthier environment for your fish.
Stones, pebbles, rocks, and driftwood are the common materials used in decorating tanks. It is important to wash them beforehand, to avoid contamination. Soak driftwood in water before placing them in the tank.

Place them strategically to improve the overall aesthetic of your tank. Many tips for aquascaping are online and tutorials on YouTube. Find what best suits your taste.
Now that you have basic knowledge of the essentials let’s further discuss other information you need in keeping an aquarium.
Before buying your Fish
When buying your fish always look for healthy ones. Make sure to buy only from reputable pet shops, those that take good care of the different kinds of fish they sell. It is important because sick fish carries bad bacteria, disease, and other possible infections that can contaminate the tank and affect other healthy inhabitants.
Some pet stores will offer fish that are best suited for your level of skill and help you choose which fish is in prime condition.
The general rules in buying fish are as follows:
- Do not buy fish from tanks with dead fish.
- Only buy fish that you are knowledgeable of.
- They should be swimming properly at the time of purchase.
- Do not buy from stores that have poorly maintained tanks.
If you are determined to give unhealthy fish from pet stores a better home then that would be all right. But make further research in treating and caring for them.
Fishkeeping is to not only have your aquarium for display but also to provide a good home for your pets.
Consider layering. Some fish are bottom dwellers, middle swimmers, and fish who likes to stay on top. This is to create a harmonious community and avoid overcrowding in the tank. Having more fish occupying the space also adds up to the overall aesthetics of your tank.
Other fish and aquatic animals are helpful in maintaining a well-balanced tank. Such as algae eaters. The production of too much algae can be bad for your tank. Snails and shrimps are great choices in keeping your tank clean and the algae growth minimal.
This is by consuming waste, algae, and others. They must also be compatible with the community you already have in your tank.
Before Adding your Fish

For saltwater tanks, the salt is added to the water and must undergo a series of cycles. Adding table salt to your fish tank is not recommended. Some pet stores sell premixed saltwater. This is to avoid having to go through the tricky process of trying to achieve the right and appropriate water salinity.
Sea salt mix is also available in pet stores. You can also get them from some online stores. They usually come with instructions for you to get the salinity level right.
What kind of water should I use in my tank?
In setting up tanks, do not use tap water. Chlorine and some minerals are not good for your fish and plants. They could be harmful and might cause some serious problems.
Water conditioner are now available in pet stores. Water conditioner get rid of chlorine and alter the condition of the water so fish can thrive.
Cycling your tank
Cycle your tank before adding in fish. Cycling can help you build up beneficial bacteria. Beneficial bacteria are important in keeping a healthy aquarium tank.
Healthy bacteria can help in breaking down the ammonia from fish waste into nitrites and turn those nitrites into nitrates. The difference between the three is the level of harm it can cause to fish. Ammonia is the most harmful and nitrate is the least harmful.
Keeping the nitrate levels of the tank in check is important because having a high nitrate level can cause rapid and massive growth of algae. Also, small amounts of ammonia and nitrites can still be harmful to your fish.
Properly acclimatize your fish. This is a step beginners often ignore. This is why there is an emphasis on research. Do not just put your fish directly to the tank. They need help in adjusting to a new environment.
There are many ways to properly acclimate your fish. The most common technique is letting the bag of the fish float at the side of the aquarium for more than 15 minutes.
By following this process:
Open the bag and pour out at least half of the water.
Secure the bag at the side of the aquarium so that it will not sink or carried around the tank. Make sure that the water from the bag and the tank does not mix.
The goal of this process is to have the water temperature of the bag with the newly-bought fish reach the same temperature as the water tank. By doing this, it reduces the stress on the fish.
This process helps them calm down. You are also slowly introducing them to their new environment, so they don’t have a hard time adjusting once you put them in.
Failing to do this may cause stress on the fish. Having your fish swimming aimlessly in the tank may also result in injuries or even death.
Setting up your tank especially for beginners is an exciting part of the process of fish keeping. After setting up your tank, remember that you consider proper maintenance and keeping the balance.
Being a fish keeper requires commitment and devotion to the hobby.
Patience is important in having a healthy tank, especially so that the process of setting up your 20 gallon fish tank is a very long process.
