Starting your own saltwater aquarium is an exciting and rewarding job/hobby. It’s no secret that keeping saltwater is a lot harder than keeping a freshwater aquarium, but it is not impossible, even when it is for a complete beginner.

The best way to realize your ideas is to plan ahead. Therefore, if you want to know everything about the saltwater aquarium kit for beginners, you have come to the right place. Stay with us and find out more.

What Size Aquarium Tank Should A Beginner Choose?

In terms of size, a newbie should not choose an aquarium tank smaller than 40 gallons. Wondering why? – The smaller the tank, the more difficult it is to maintain stable water parameters. Accordingly, the larger the tank and thus more stable, the easier it is to maintain a thriving saltwater ecosystem.

Also, many are often fooled when they think that a larger aquarium tank requires more maintenance. Namely, when the need for attention is calculated, it decreases with the number of gallons, which looks like this:

  • a 5-gallon aquarium requires attention every day,
  • 20-gallon aquariums need attention every few days,
  • a 40-gallon tank needs attention once a week,
  • 125-gallon tank should be addressed every two weeks.

Parameters such as ammonia, phosphates, or nitrates grow more drastically in smaller environments and so can harm or kill your fish and coral faster. The reason for this is the small amount of water in which the negative aspects of the accumulation of fish waste, uneaten food, and dead matter are much more strongly felt. Eventually, as you can imagine, your saltwater tank can be deadly.

Things A Saltwater Aquarium Kit For Beginners Should Include

Aquarium Lightening

Lighting is one of the incredibly important things for maintaining a healthy aquatic life. Why? This is because your plants use light to create food for themselves, and fishes and corals require sunlight to thrive. Lastly, good lighting can make your saltwater aquarium look really nice. As for the type of light itself, it will depend on the type of system you plan to set up, as well as what kind of livestock you will keep inside your aquarium tank.

Skimmers, Filters & Filtration Equipment

The installation of a protein skimmer is certainly the most popular filtration solution for a saltwater aquarium. Its role is to remove fish waste, uneaten food, and other organic matter before it begins to decompose into harmful by-products. As for the types of protein skimmers, they can be in the form of hang-on types or in-sump types suitable for all dimensions of the aquarium.

The rest of the equipment also depends on the type of system you are going to set up. There are various saltwater aquarium kits for beginners on the market today that include everything you need to start this hobby.

Powerhead is one of the components that every saltwater aquarium kit for beginners must include. Its purpose is to direct the flow towards low-flow areas where fish waste and other detritus tend to accumulate.


Substrate & Live Rock

The substrate is considered to be one of the most important parts of your aquarium. Therefore, choosing the right one is the key to the health of your underwater world. You can choose between different colors, types, densities, and sizes of materials.

Many marine animals tend to be territorial, so it’s important to provide ample shelter or places where animals can sleep and hide from other tankmates.

Sea Salt, Heater & Thermometer

As you can guess, sea salts are what make aquarium saltwater. They are often called salinity testers because they measure the specific gravity or salt content of water.

Every aquarium needs a good heater. If you opt for a smaller aquarium, one heater will suffice. Larger tanks, on the other hand, require the use of multiple units. As a general rule, 3 to 5 watts per gallon is recommended for a saltwater aquarium. Also, don’t forget to get a pair of thermometers as they are the key to regulating and maintaining heat at the proper temperature.

Final Words

After all, in order for everything to work properly and be in the right range, you will need to have a regular maintenance regimen. Setting up your aquarium correctly the first time makes a big difference because it simplifies the maintenance regime.

Trust us, with prior planning and dedication to this hobby, even a beginner can keep everything swimming smoothly.
