The basic principle and components of Aquarium Life Support System: Aquarium Life-support system is the abbreviation of life maintenance system, which uses modern aquarium technology to imitate the natural environment to create an artificial water environment for cultured organisms.

Here are six components of the aquarium life support system:

  1. Chiller and Heater – Constant temperature control system
  2. Pump – Circulation system
  3. Mechanical filter – Mechanical filtration system
  4. Protein Skimmers – Protein separation system
  5. UV Sterilizers – Sterilization system
  6. Biochemical Filter – Biochemical filtration system.


Components of Aquarium Life Support System


Lando Aquarium Cooling and Heating System comes in a variety of sizes and uses a titanium coil design, which makes them ideal for all saltwater aquariums. It supplies the ultimate in aquarium temperature regulation. They are also known for being quiet to operate, With high efficiency, long service life. make sure that the wattage can handle the volume of your system and don’t buy a cheap one. For more information about chiller and heater. Please visit here.

Main function: Since most of the fish and creatures kept and displayed in aquariums are from tropical and subtropical waters, they have high requirements for water temperature. So there must be an effective heating control system to ensure the stability of water temperature.



To develop their own normal water temperature fluctuation range according to the different fish species, can not be generalized.
The fluctuation range should not be too large, to take into account the impact on the nitrifying bacteria, 24-hour adjustment range is best to control within 2 ℃.

Short-term fluctuations in water temperature are too large for fish health damage, to avoid as much as possible, once this situation to deal with in a timely manner.


  • Pump – Recirculation system of aquarium life support system

The original circulation system is to uses the pump as the power to push the water body to flow continuously between the closed pipe channel equipment and the display pool. It enables the polluted water to be transformed into an environment suitable for the normal growth of aquatic organisms after mechanical filtration, protein separator, biochemical filtration, disinfection equipment, and constant temperature equipment.


  • Mechanical filter -The mechanical filtration system of the aquarium life support system


The role of a mechanical filtration system is to remove insoluble suspended pollutants, including residual bait, carcasses, secretions, excretions, and other substances in the water body through various filtration equipment. To improve the transparency and reduce the burden of the protein separation system.


  • Protein Skimmers – Protein Separation System of the aquarium life support system

The protein separation system mainly includes a protein separator, protein separation pump, venturi jet, and venturi pump. Using the pump high-pressure pumping and the air brought in to produce a large number of small particles bubbles, the proteins, various suspended particles, dead microorganisms, etc. in the water are adsorbed up to the surface of the foam and brought out. After a column cylinder upward push up and be discharged, so that the insoluble proteins, amino acids, fatty acids, carbohydrates, enzymes, organic debris, algae material, inorganic compounds, protozoa, etc. are finally removed, and the protein separation system operates normally to ensure a suitable environment for aquatic life.


  • UV Sterilizers – Germicidal system of the aquarium life support system


The strong oxidizing power of ozone is used to oxidize the proteins on the cell wall or body wall of bacteria, fungi, viruses, and parasites to kill bacteria.
The main role of ozone.
1. Sterilization.
2. Deodorization.
3. Oxidation.
4. Oxygenation;
5. Improve the quality of the water



The amount of ozone used needs to be strictly controlled; not overly dependent on ozone.


  • Biochemical Filter – Biochemical filtration system of aquarium life support system

The biochemical filtration system is the most critical system among the six operating systems. The quality of water and the health of fish depend on the design effect of the biochemical filtration system, which is the core system of the aquarium. It is impossible for inland aquariums to change a lot of seawater, the role of the biochemical filtration system is to turn “stagnant water” into “living water”, to turn biologically used water into “good water”, and to turn toxic water into less toxic water. high water quality into low toxicity water, to ensure the long-term recycling of seawater.


The biochemical filtration system is specially designed with a biochemical pond, which has a large number of biochemical materials: such as coral sand, biochemical ball, ceramic ring, biochemical cotton, and so on. On the surface of these biochemical materials, there are a large number of microscopic pores for biochemical bacteria to attach and grow. These biochemical bacteria (such as nitrifying bacteria, nitrosobacteria, anaerobic bacteria) are beneficial bacteria, and play a role in improving water quality.

The main role:

these beneficial bacteria in the biochemical pool constantly nitrification and denitrification, nitrifying bacteria, and nitrosating bacteria in the nitrification process will be highly toxic ammonia nitrogen into nitrite and then into the basic non-toxic nitrate.


Nitrifying bacteria and nitrating bacteria because of their own poor ability to compete for oxygen, and need a lot of oxygen, so the top of the biochemical pool is equipped with a sprinkler so that more oxygen in the air to the water for these bacteria to use.

Nitrifying bacteria and nitrating bacteria are mainly growing in biochemical cotton, biochemical ball, the surface of coral sand, forming a film, while anaerobic bacteria (denitrifying bacteria) is growing in the deepest pores of coral sand, do not need oxygen, in the denitrification process will convert nitrate into nitrogen gas, discharged into the air.


Lando Aquarium Chiller project



Marine life from nature to the oceanarium, the first problem is to survive, the environment of the aquarium pool determines the survival, growth, and reproduction of marine life. Natural scenery, maintenance of water quality and lighting control, water temperature control, etc., is to meet the necessary conditions for the survival of marine life; these conditional factors are the core of the entire oceanarium, the soundness of the maintenance system or not, directly related to the display effect of the oceanarium and the health of the animals, its decision on the success or failure of the operation of the oceanarium.
