What Equipment Do You Need for a Marine Fish Tank? (17 Essentials)


So you’ve made the exciting decision to get into the hobby of keeping marine fish in an aquarium. Now is the time to begin putting together the gear that you will want in order to make your saltwater fish tank ready for fishing and set up properly. I have compiled a list of the fundamental components that must be present in your saltwater fish tank before it can be put into operation. There is always going to be some dispute about what is necessary and what isn’t, but I believe that this is a very solid list of the things that are considered “must-haves” when it comes to putting up salt water fish tanks.

  1. Ground Fault Circuit Interrupter (GFCI) – Electricity and water do not go well together. Always remember to put one of these in each wall outlet that will be used for your tank and ensure that it is properly installed. The fact that you may plug anything into any electrical outlet means that this is not technically necessary; yet, the danger involved is not worth it. A GFCI might potentially save a person’s life.
  2. A power strip with a surge protector — With heaters, lights, skimmers, and other pieces of equipment, you’re going to need more than two outlets for your tank’s equipment. Make an investment in a high-quality power strip that not only allows you to plug in all of your equipment but also has surge protection to prevent your supplies from being ruined.
  3. Tank – A marine fish tank is impossible to have without the tank! My recommendation is that you get the greatest size tank that your budget will allow you. Find out what size fish tank you need by reading the information provided in this article.
  4. Tank stand – In order to complete the process of setting up your saltwater fish tank, you will need sturdy fish tank stands. This is because fish tanks can become very heavy when they are filled with water, so you need to ensure that your tank is placed on a stable foundation. In addition, salt water fish tanks may leave a salt residue on the exterior of the tank, thus placing them on a piece of furniture or a counter may promote corrosion and create a messy situation.
  5. A Deionizer or a Reverse Osmosis Unit – Regular tap water is not sufficient. Your marine fish tank and the inhabitants in it need water that has been treated with either a reverse osmosis (RO) unit or a deionizer in order to maintain a high level of water quality.
  6. Salt mixture — A saltwater fish tank is impossible to have without the addition of salt. There is a wide variety of salt mixtures on the market that may provide not only the salt but also the other components that the residents of your tank need.
  7. Hydrometer – This nifty little instrument will enable you to determine the specific gravity of the salt water in order to ensure that it is at the appropriate level.
  8. Test kits – Because fish kept in saltwater aquariums are very sensitive to changes in water parameters, it is essential to remain on top of everything and check the water quality on a consistent basis. Regular testing for pH, ammonia, nitrates, and nitrites is a bare minimum need for maintaining a healthy environment in your aquarium. You might take some water samples to the local aquarium store, and if the employees are helpful, they could even analyze them for you at a reduced or even free cost. However, when the tank is being cycled for the first time, you should be checking the water on a daily basis; however, it will be somewhat difficult for you to bring water samples to the store on a regular basis during this time.
  9. Buckets, Towels, Rubber Gloves – It is essential to have buckets and towels on hand while maintaining a marine fish tank since the process of changing the water, cleaning, and adding new inhabitants may become wet and muddy. You and the other residents of your tank will be safeguarded by the gloves.
  10. Substrate: Although this component is not strictly required, it is highly recommended that you fill the base of your aquarium with either crushed coral or living sand. When putting up a marine aquarium, there are many different kinds of substrate that may be used. The fact that sand is a natural substance and will make the occupants of your tank feel more at ease is the single most significant consideration when setting up a saltwater fish tank. Sand, on the other hand, has a more attractive appearance than gravel does.
  11. Live Rock, Ornamental Rocks or Coral Your fish will need some rocks or other decorative materials in the tank so that they have a place to hide and feel comfortable. This may be done by adding either decorative rocks or live rock. You may find out how much saltwater live rock you need by clicking this link.
  12. Heater: Given that you will most likely be maintaining tropical kinds of fish, you will need a heater to ensure that the water is of an appropriate temperature for them.
  13. A thermometer, since you will need to determine whether or not the heater is performing its function properly.
  14. Lighting – There are a few different choices available for the lighting. What you want to put in the tank will determine which option is best for you to go with (i.e., a fish only tank will not require the lighting intensity as a reef tank with live rock and coral).
  15. Powerhead: A high-quality powerhead will generate significant currents in the water of the aquarium. This is crucial because it mixes the water in the aquarium, removes any dead or stagnant regions, and assists in maintaining the health of your fish. When combining salt for water changes, you could also find that you need an additional powerhead to utilize.
  16. Protein Skimmers Skimmers remove organic waste from your aquarium before it can decompose and convert into nitrates, which are harmful to saltwater aquarium fish. Nitrates are produced when organic waste breaks down. Protein Skimmer, commonly known as foam fractionating, is a crucial component in maintaining the overall health and happiness of your marine aquarium. You will need to make an investment in a protein skimmer of sufficient grade if you wish to maintain a low level of dissolved organic compounds (DOCS).

Skimmers remove undesired organic molecules from the water before they decompose and contribute to an increase in the levels of ammonia, nitrate, and nitrite. It literally removes the “gunk” out of your tank, and after a month of usage and seeing all of the material that accumulated it, you will soon realize how useful this piece of equipment is. A protein skimmer is one of the most crucial things you can acquire for your aquarium.

  1. Fish – A marine fish aquarium is not complete without the aquatic inhabitants! Be sure to make an informed decision, not to overcrowd your aquarium, and to avoid purchasing animals of different kinds that cannot coexist.
