Everything You Need to Start a Saltwater Aquarium at Home

Aquarium/Tank & Stands

Once you have decided where you are going to place your new aquarium, you will need to choose a tank that will fit the available space. Fortunately, there will probably be several different tank sizes and styles that will work for you.

While you are shopping for your new tank, keep an eye on what equipment (filtration, lighting, etc.) is included. Buying an aquarium package or "kit" can save you a lot of time and money as everything included is designed to fit the tank. For smaller spaces, the plug n' play mini/nano aquarium kits are a quick way to get almost everything you will need to get started. For larger spaces, a 1–50 gallon aquarium might work for you. If you have the space and desire, one of the show-size display aquariums might be just the ticket.

For those who want to design your own tank and save money at the same time, you might want to explore the DIY aquarium route. Building your own aquarium is remarkably easy to do.

While you are shopping for your new aquarium, keep in mind that you will need something to put it on. Many of the packages include an aquarium stand; if not, there are a number of manufactured aquarium stands and cabinets to choose from.

Aquarium Lighting

The type of lighting you choose will be based on the type of system you have planned to set up, as well as what kind of livestock you will be keeping in it. If you are not purchasing an aquarium kit or package, you will have to select your tank lighting.

Fish-only tank lighting is less expensive while reef tank lighting and coral lighting are a bit more involved and pricey. While shopping for lighting, keep in mind that you may want to upgrade your tank from a fish-only to a reef tank in the future. Buying fixtures that can be retrofitted with more powerful bulbs in the future might be a better buy in the long run.

If you are interested in a long (and even short) term money saver, look into the LED light fixtures. These sleek, compact, and efficient fixtures are now available with reef-grade bulbs. You will also find that using a power center to control your lights and other electrical equipment will greatly simplify running your new aquarium.

Protein Skimmers, Filters & Filtration Equipment

Filters & Filtration Equipment

If you have not purchased an aquarium kit (package), the type of system you are going to set up will help you determine which kind of filters and filtration system to choose.

• Choosing a filtration system is the next step in putting your new aquarium together.
• Canister filters can be used with almost any type of system.
• Wet/dry trickle filters have the advantage of being modified to meet almost any demand.
• Power filters are usually hung on the tank and are easy to use.

Protein Skimmer

Protein skimmers remove dissolved organic compounds (DOCs) directly from the aquarium system water before they are processed by the biological filter. While not essential to an aquarium filtration system, many people find that skimmers do take a lot of the load from the biological filter, allowing a larger fish and invertebrate population in the tank.

Just take note: Before purchasing a protein skimmer, you will need to determine where it will be placed in your system.

Powerheads

Depending on the size of your aquarium, the use of one or several powerheads is an excellent way to provide good water circulation throughout the system.

Substrate & Live Rock

Substrate

Substrate is more than just the stuff at the bottom of the tank, so choosing the right substrate for your aquarium is important. There are a number of different colors, types, densities, and sizes of materials used for aquarium substrates. If your tank has strong water currents, choose a heavier substrate to prevent displacement. For substrates that serve as a significant part of the biological filter, focus on options with higher porosity and surface area.

If you choose to use a Jaubert Plenum filter, you will want to use live sand that is suitable for a deep sand bed.

Live Rock

Live rock plays an important role in a marine tank. Many marine animals, fish in particular, can be quite territorial. It is important to provide ample shelter or places where the animals can hide, sleep, and avoid potential problems with aggression from other ​tankmates in the confined space of an aquarium.

Sea Salt Mix/Saltwater & Hydrometer

Sea Salt Mix/Saltwater

Sea salts are what make an aquarium a saltwater or marine aquarium.

Hydrometer

Also referred to as a salinity tester, this item measures the specific gravity or salt content of the water.

Heater & Thermometer

Heater

For smaller aquariums, one heater works well, but for larger systems, the use of multiple units is advised.

Thermometer

With stick-on, floating, multi-function remote digital sensors, and many other types of units to pick from, the material a thermometer is made of is an important factor when choosing one as well.

Test Kits, Additives & Supplements

For live rock and reef tank systems, calcium (a.k.a. limewater/kalkwasser) needs to be added. Other supplemental vitamins or additives that are beneficial to the health of certain marine inhabitants you may be keeping, such as iodine for crustaceans, are important as well.

Air Pump & Air Stones

Air pumps and stones are generally needed only for equipment like counter-current protein skimmers because air bubbles in saltwater aquariums cause salt creep.

Maintenance Tools & Supplies

This category includes having items on hand such as various-sized plastic buckets or containers, tank cleaning tools such as a siphon tube/hose, an algae scraper or magnet, as well as nets of different sizes, spare equipment replacement parts, and so on. A good way to keep track of what maintenance tasks you have performed and when is to keep a log book or record of everything you do.
