The anti-gas lift filter can cultivate enough nitrifying bacteria to consume the harmful substances ammonia and nitrous acid in the fish tank and generate non-toxic nitric acid, so as to achieve the filtering effect.

The gas is provided by the air pump, and the air pump stone is placed at the bottom of the anti-gas lift filter. The air flow is from bottom to top, and the water flow is from top to bottom, which is conducive to the fusion of water and oxygen, and improves the nitrification efficiency of nitrifying bacteria. And the gas is the reverse flow, so it is called the anti-gas lift filter, which is the difference between it and the gas lift.

 (Gas lift is that the upper mouth is lower than the water surface, and does not receive the upper filtered water, but uses the natural rise of gas to drive the water to flow upward, and the bottom is the water inlet hole.)

The anti-gas lift filter has a powerful function of adsorbing fine particles and is a powerful tool for controlling water turbidity. Anti-gas lift filters are generally considered to be just an enhanced biochemical filter. The general concept holds that the biochemical effect of the trickle is the best because it is in complete contact with the air. 

But the posts comparing trickle and anti-gaslift filters seem to have no examples where trickle is stronger than anti-gaslift filters. For example, the water is so clear that there is almost no water. In major forums, there are posts about anti-gas lift filters, but drip and bottom filters are rarely seen.

Why, I am afraid to find out from the principle. The trickle is the natural contact with the air when the water is dripping, while the anti-gas lift filter is the contact between the glass ring and the forced rising air bubbles when the water is falling. 

Obviously, the latter has a larger contact area and longer contact time than the former, which is more conducive to nitrification. Bacteria work. But this is just a biochemical process and does not mean that the water is better than the trickle. So whether the anti-gas lift filter has a physical filtration process at the same time.

We know that filter cotton can only filter larger particles. When we look from the side of the fish tank, there are often many tiny suspended particles in the water. These are the most critical factors affecting water clarity. The impeller of the water pump often smashes the stolen goods, and many tiny particles that cannot be absorbed by the filter cotton appear. So some fish tanks look foggy. The reason why the anti-gas lift filter works well is that it must solve these tiny suspended particles.

We know that the glass ring and ceramic ring inside the anti-gas lift filter are objects with numerous micropores and huge surface area inside. And such objects have a strong adsorption of particles (like activated carbon). 

When the anti-gas lift filter is working, a large number of air bubbles prevent the water from leaking down, and the water is broken up into countless tiny water droplets that move between the glass rings or ceramic rings. long. So the particles in the water are fully adsorbed by the glass ring or ceramic ring. The last water that flows out is extremely clear water.

Therefore, it is concluded that the anti-gas lift filter has a strong physical filtration function in addition to biochemical filtration. At the same time, it shows that the glass ring and ceramic ring in the anti-gas lift filter have a lifespan. After a certain period of time, the pores are full, and the filtering effect will be poor, and it should be replaced at this time.

Some friends will say whether activated carbon is better. Activated carbon is better for drinking water, but for fish tanks, the adsorption capacity is limited due to the larger particles and the smaller pores of activated carbon. So glass rings and ceramic rings come in handy.

Rotten aquatic plants leaves, dead fish, unfinished feed, dead algae and fish feces are decomposed by some saprophytic bacteria, and organic nitrogen is turned into inorganic ammonia. Just like a fish that has just died has no taste, when it is putrefied, it will produce a pungent stench, and here is the smell of ammonia. 

Ammonia is highly toxic to fish, it can denature the protein in the blood of fish and lose its physiological function, resulting in the death of fish. When the ammonia concentration in the water body exceeds 0.2ppm, it will cause acute fish death.               

So, what to do if there is pollution in the water? At this time, we need to cultivate nitrifying bacteria to decompose most of the toxic substances. The anti-gas lift filter is one of the biochemical filter equipment used to cultivate nitrifying bacteria.

The nitrifying bacteria in the anti-gas lift filter are aerobic bacteria, and they also consume oxygen themselves. Generally, an air pump should be added to the anti-gas lift filter to support them. Because the filtration system decomposes impurities and corrosive substances, there are fewer impurities in the water, so the oxygen capacity of the water coming out of the filter is improved. 

(If there are impurities, feces, etc. in the water in the tank, the impurities will biodegrade under the action of aerobic bacteria, and at the same time, the dissolved oxygen in the water in the tank will be consumed, and the excessive pollution of the water will lead to the lack of oxygen).

1. Compared with other filter materials, the anti-gas lift filter has the advantage that it provides convection between water and gas (supplied by air pump), which makes nitrifying bacteria who like sufficient oxygen live more comfortably in it. It works well with other filter media.

2. However, the number of fish and the amount of poop discharged should be considered. Insufficient food for nitrifying bacteria inhibits bacterial growth in numbers. (If the excrement itself is small, the number of nitrifying bacteria is limited, so no matter how large the filter is, the room is empty, but the fish tank space is wasted.)

3. The structure of the anti-gas lift filter is very simple, generally made of a plastic cylinder with a diameter of 16 cm. Put the stone into the bottom of the cylinder, and then put a glass ring with a capacity of 80%. Place the anti-gas lift filter under the upper filter and the lower water outlet to catch the upper filter drainage. The cylinder must be 2 to 3 cm above the water surface. Start the air pump to pump up even if it is running normally.

This product can not only filter impurities in water, suck fish feces, but also increase oxygen to provide a healthy living environment for your lovely pets. Internal triple effective in-line filtration, sand will block a large number of particles in the water, sponges can absorb residual substances, and activated carbon can make the water clearer. This mini filter box is suitable for small fish tanks and does not take up space. Easy to disassemble and clean. It needs to be used with trachea and oxygen pump (not included).

The anti-gas lift filter is a biochemical filter used to filter the water quality of the aquarium. The principle of the anti-gas lift filter is the convection of water and air. The anti-gas lift filter is generally placed on the upper filter Below the water outlet, the falling water from the upper filter is accepted. Moreover, the anti-gas lift filter is generally a large opening, and its upper end is higher than the water surface.

 In this way, the effluent from the upper filtration will all flow into the anti-gas lift filter, and the water flow will flow out from the water outlet at the lower end of the anti-gas lift filter with a certain pressure (because the opening is higher than the water surface).

The bottom of the anti-gas lift filter is the water outlet. The anti-gas lift filter is generally placed below the water outlet of the upper filter to receive the falling water from the upper filter. Moreover, the anti gas lift filter is generally a large opening, and its upper end is higher than the watersurface. 

In this way, the effluent from the upper filtration will all flow into the anti-gas lift filter, and the water flow will flow out from the water outlet at the lower end of the anti-gas lift filter with a certain pressure (because the opening is higher than the water surface).

In this way the glass ring can be affected by both the descending water flow and the ascending air bubbles. Compared with ordinary gas lift, the anti-gas lift filter not only has more convection, but also its internal water flow is much larger than that of ordinary gas lift. 

Therefore, for culturing nitrifying bacteria, the anti-gas lift filter is undoubtedly stronger than the ordinary gas lift, and there are even aquarists' reactions. The effect of using the anti-gas lift filter is better than that of the filter barrel.
