Equipment for Filtration and Lightening

Filtering and lighting your water is an important step in maintaining a well-rounded home care routine. Utilizing the right equipment can make this process easier and more efficient.

Different filtering options come with unique technical specifications, making it possible for every household to find a solution tailored to their specific needs. From countertop filters to whole house systems, learn how the right filtration and lighting equipment can positively impact your home environment.

Filtration System

A filtration system is essential for maintaining water quality and providing a healthy environment for your aquarium inhabitants. Common types of filter systems include hang-on back filters, canister filters, power filters, under gravel filters, wet/dry trickle filters, and more.

Protein Skimmer

Protein skimmers help to remove dissolved waste, bacteria, and other organic compounds from the water column. This helps to keep the aquarium clean and healthy, reducing nitrate and phosphate levels.

Heaters and Chillers

Heaters are used to maintain a consistent temperature for your tank, while chillers can be used to reduce temperatures in warmer climates.


Proper lighting is essential for triggering the growth of coral and other invertebrates in your reef tank, as well as providing a stimulating visual display. Different types of lights to consider include LED, T5 fluorescent, and metal halide bulbs.

Water Pumps

Water pumps are used to provide water circulation, oxygenation, and waves throughout the tank, creating a more natural environment for your fish.

Test Kits

Test kits are necessary for monitoring water parameters such as pH, alkalinity, ammonia, nitrite, and nitrate levels. This will help you to maintain a healthy aquatic environment for your fish.

Aquarium Salt

To create a saltwater aquarium, you need to add an appropriate amount of aquarium salt to the tank water. This helps to maintain the correct salinity levels and provide minerals for your fish.

Equipment for Filtration and Lightening


Selecting the Right Substrate

When it comes to selecting the right substrate for a saltwater reef tank, you’ll want to look for materials that are natural and that help maintain the chemical balance in your tank. Aragonite is one of the most popular choices as it helps maintain calcium levels and keeps water alkalinity consistent over time.

Natural coral sands provide both aesthetic appeal and necessary microorganisms that benefit the residents of a saltwater reef tank, while special mixes like crushed coral or live sand may be best suited for tanks with more aggressive fish species.

Ultimately, choosing the right substrate will depend on what type of creatures you plan to house in your tank – so research carefully before making any decision.


Substrate Type Properties Suitable for
gravel Inexpensive and easy to clean, available in a wide range of colors and sizes. It also allows water to move quickly through the substrate.
Community Aquariums, Goldfish tanks, Fish only tanks.
Sand Non-abrasive on fins, cushions fish as they swim close to the surface of the substrate tank. Low maintenance and perfect for bottom-dwelling fish like Loaches, Eels, or Catfish. It does require regular vacuuming to remove debris.
Live plants tanks, Bottom-dwelling fish tanks.
Clay Pebbles or Beads Allows for great water circulation while allowing roots to receive oxygen from water movement between them. Easy cleaning with a small siphon tube when performing regular maintenance.
Platy fish tanks, Live Plants Aquariums.

Selecting the Right Substrate


Selecting Livestock

When it comes to selecting livestock for your saltwater reef tank, a bit of research and planning will go a long way. After ensuring that the equipment necessary for a healthy, sustainable tank is in place, it is time to think about which coral and fish species best suit your individual setup and interests.

Consider carefully the types of creatures you want to house as well as their particular needs so that they can thrive in their new home.

Livestock type Characteristics Suitable for
Corals Require certain water conditions and temperature, require strong lighting, and appropriate water flow. Different species of corals grow at different rates and need to be fed specific nutrients.
Marine tanks with stable pH levels, high-intensity lighting, and good circulation.
Fish Choose slow-moving fish that are compatible with each other in terms of size and temperament. It is best to research the species before adding it to your tank as some fish may not be suitable for a reef tank environment.
Saltwater aquariums with a variety of sizes and temperaments.
Invertebrates Most invertebrates are sensitive to changes in their environment, so stability must be maintained. They also need regular feeding since they mostly eat plankton or microalgae which are not usually found in a reef tank naturally.
Stable marine tanks, with the right food sources available for them.

Tank Maintenance

Tank Maintenance

Establishing a Proper Water Chemistry

Maintaining proper water chemistry for a saltwater reef tank is essential for the health of your tank’s inhabitants. Testing and monitoring the parameters of your tank water regularly, at least once a week, ensure that elements such as salinity, alkalinity, nitrate, and pH are all properly balanced.

Changing out 10-15 percent of your tank water every two to four weeks with dechlorinated fresh water can help maintain proper water chemistry. It is also important to select additives and treatments with caution to avoid any disruption in the water chemistry.

For example, you should use calcium and alkalinity balancing treatments specifically designed for aquaria and buffer the alkaline levels of your aquarium accordingly. With careful attention to the ongoing maintenance needs of your aquarium’s environment, you will be able to maintain a healthy reef tank.


Cleaning and Monitoring the Tank on a Regular Basis

Maintaining a saltwater reef tank is a rewarding experience, but it also requires consistent cleaning and monitoring to ensure that everything is working properly. Regular tank maintenance should begin as soon as the tank has been set up with the necessary equipment and species.

Cleaning the filtration system, substrate, decorations, and tank walls can be done on a weekly basis, or when odors or excessive algae become present. Monitoring ammonia, pH, nitrite, and nitrate levels are also essential to clean water in the aquarium and healthy fish; it is best to test these levels three times a week at least.

Additionally, regular water changes should be completed once a month or at least every six weeks – this not only helps maintain ideal water chemistry but keeps your living environment looking fresh and beautiful as well.

Cleaning and Monitoring the Tank on a Regular Basis


Feeding Your Livestock

For beginner aquarists, maintaining a saltwater reef tank can be daunting. Feeding your livestock is an important step in keeping their environment healthy and successful.

To feed your livestock properly, it is essential to provide them with a balanced diet that includes both herbivorous and carnivorous foods as well as vitamins and minerals to ensure they get the nourishment they need.

It is also important to remember that not all tanks contain fish or coral and each of these organisms has different requirements for nutrition and overall health. Experienced aquarists often recommend considering the various diets required for different livestock as well as researching specific nutritional needs for individual species.


Dealing with Pests and Diseases

When setting up a saltwater reef tank, proper pest and disease management is essential for maintaining the health of aquatic life. The most critical step in preventing pests and diseases is to carefully quarantine new fish or corals for at least four weeks.
