How an Oxygen pump Air Compressor working - 3 minutes for reading
The principle of the oxygen pump is to press air into the water so that the oxygen in the air can fully contact the water body, so the oxygen can be integrated into the water, thereby increasing the dissolved oxygen content of the water body to ensure the growth of oxygen-consuming organisms. Because of their convenient and efficient use and low cost, oxygen pumps air pumps are widely used in modern fish farming.
The oxygen necessary for fish to survive is obtained by absorbing dissolved oxygen in the water through the capillaries of the fish's gills, and then brought to and picked up by the blood circulatory system, and the carbon dioxide discharged is also carried out through the capillaries of the gills. The amount of dissolved oxygen in the water directly affects the growth of fish, so it is necessary to ensure that there is enough dissolved oxygen in the water. In addition to obtaining dissolved oxygen in water by mixing and changing water, water plants in the water can also be used for photosynthesis to produce oxygen.
In theory, 1cm of fish can be raised per liter of water, and there is no need for oxygenation in normal climates. The size of small fish tanks is relatively small, so due to space constraints, there will not be too many fish, so there is generally no need to consider the oxygen content in the bathtub.
That is to say, generally small fish tank oxygen pumps are not needed. As long as there are not too many fish stocked, the filter system can be done well, and the flow of water can play a certain role in increasing oxygen. However, if the air pressure is low, such as when the dissolved oxygen is insufficient during the rainy season, oxygen is needed to prevent the fish from suffocating.
How to choose a fish tank oxygen pump
The fish tank submersible pump is an important part of the fish tank filtration system and one of the key factors that determine the water quality of the fish tank. The root cause of many fish diseases is that the pump power of the fish tank is too small and the breeding density is too high. As a result, the filtration system cannot decompose the harmful substances in the fish tank in time, such as ammonia nitrogen, and nitrite. The poor water quality in the breeding of bacteria and parasites. The result is that the fish keep getting sick. Therefore, it is very important to choose the right pump.
Choose the right pump power. The factors that need to be considered when choosing a water pump are the size of the fish tank, the form of filtration, the richness of the filter material, the density of the fish, the size of the fish, the type of fish, etc. Generally speaking, the larger the aquarium capacity, the smaller and simpler the filter material, the greater the breeding density, the larger the size of the fish, and the faster the metabolism of the fish in the species, the higher the power of the pump is suitable.
Configure the water pump according to the size of the tank. When raising medium and large fish in the finished tank filtered by the common top tank, it is more appropriate to configure a water pump of about 25 watts per 100 liters of tank capacity. For example, if the length of the fish tank is 1.2 meters, the width is 0.35 meters, and the water level is 0.5 meters, then the water capacity of the fish tank is 1.2*0.35*0.5*1000=210 (liter), you can consider to equip two pumps of about 25 watts, or equip 45 A single pump about watts (also consider dividing into 2 water outlets, one creates flow directly in the tank, and the other introduces water into the top tank to filter).
Breeding density. At present, most of the supporting water pumps of the finished cylinders sold on the market have low power and simple filter materials, and the general water pumps cannot reach the rated power and flow rate indicated by it. When novices raise fish, most of them prefer a higher breeding density and feeding frequency (hope that the fish grow up quickly), and it turns out that the fish start to get sick and die soon after they are raised. The main reason is that the breeding density, species, and feeding frequency need to be matched with the size of the tank and the strength of the filter system. An important way to improve the filtration system is to re-match your fish tank with a suitable pump.
