Which filtration method is good for fish tanks?

Question 1: Which fish tank filter is better? Now many friends like to raise fish at home, which can adjust their mood. In order to keep the water in the fish tank clear and clean, and the oxygen is enough for fish to grow, they have to use the fish tank filter. Which is better? There are many kinds of fish tank filters in the market, which are beautiful in appearance. They can not only clean the environment of the fish tank, but also decorate the fish tank to achieve the purpose of beautification. Let's see what they have.

1, barrel external filter

Generally, a closed barrel filter is placed outside the fish tank container. For different filtering effects, different filtering materials can be placed according to different needs.

Barrel-shaped external filter.

Advantages: no space occupation, beautiful appearance, low noise, more filtering villages can be placed and the filtering effect is good.

Disadvantages: cleaning is troublesome and expensive, and it is only suitable for larger fish tanks.

2. Air-lift biochemical cotton filter

Biochemical cotton is fixed at the entrance of the water pump, and the water flow is forced to circulate in the biochemical cotton by the water pump, and air is mixed into the water flow to increase oxygen according to the jet principle. Organic substances such as bait and biological excreta left in water can be adsorbed on the surface of sponge. Air lift biochemical cotton filter.

Advantages: simple structure and low unit price, and can be directly used for fish tank water.

Disadvantages: the filtering principle is simple and the effect is poor. Biochemical cotton should be washed frequently, which will affect the viewing in the fish tank. It is suitable for the over-action of small fish tanks in the breeding period and isolation treatment period, but it has little effect when the water quality is too dirty.

3. Fish tank filter with styling

Multi-functional filtering device adopts emerging technologies such as invisible filtering device, ecological imitation principle, etc., and comprehensively applies ecological imitation filtering principle internally, with beautiful external design, decorating the fish tank and directly putting it at the bottom of the fish tank for use.

Advantages: beautiful appearance, not only can filter and replenish oxygen, but also can decorate the fish tank, which does not affect the appreciation. The bionic filtering principle is adopted, which has good filtering effect and prolongs the water change time to the maximum extent; Simple and convenient to use, directly placed at the bottom of the fish tank.

Disadvantages: it is not easy to be too big and not suitable for large fish tanks.

4, aquarium top filter

This is a filtering device placed on the top of the aquarium. The water in the aquarium is pumped into the filter box with a filter layer by a small water pump, and the water flows back to the aquarium through the filter layer, thereby removing impurities contained in the water and purifying the water quality.

Advantages: the space at the top of the aquarium can be fully utilized, and the daily maintenance and cleaning are convenient.

Disadvantages: the filter device is placed on the top of the fish tank, which affects the viewing from top to bottom and is not suitable for looking back fish culture.

Having said that, it depends on which one you want to choose.

Question 2: What is the best filtration method for fish tanks? The bottom filtering fish tank has the best filtering method.

The bottom filter fish tank is an evolved version of the top filter fish tank.

The effect of bottom filtration and filtration cycle is obvious.

But the price is a little more expensive than the fish tank.

There is no need to change water for a long time.

Fish tanks can always be kept clean.

Suitable for family farming of tropical fish.

Question 3: What is the best filtering method for fish tanks? At present, the bottom filtration has the best effect, but you should choose according to the fish you need to raise.

Question 4: What is the best filtration method for my fish tank? It is more efficient and does not need to give fish tanks. At the same time, it does not need to add oxygen to the water. The disadvantage is that it is higher than the fish tank and affects the appearance. Once the power is cut off and there is no water, nitrifying bacteria will die quickly and make a lot of noise.

The fish in the side filter and the post filter have high density and need extra oxygen to occupy the space in the tank, but the power failure time is slightly longer, which is not a big problem because the water in the filter can provide oxygen for nitrifying bacteria for a long time.

The advantage of bottom filter is that it does not occupy any space in the cylinder and has low noise. The disadvantage is that impurities at the bottom of the cylinder cannot be sucked out.

Question 5: Which filtering method is the best for a large fish tank depends on the size of the fish tank you use.

Filter barrels are recommended for fish tanks over one meter.

Advantages: there is no space in the cylinder, disadvantages: energy consumption and equipment cost need to be increased;

DIY gas lift prevention is recommended for large fish tanks.

Advantages: strong filtration effect, huge filter material volume (more than 50 high 1 10PVC pipes, filter material volume is about 6 kg), which can be fully utilized. It is a perfect choice to cooperate with the upper filter, which is responsible for the physical filtration and biochemical filtration of the first layer, and the reverse air lift dominates the second biochemical filtration. Disadvantages: it will waste some space in the cylinder, but

Question 6: What is the best fish tank filtration? It is best to use external filtering. The N-layer lattice you are asking is external filtration.

Filters don't need to be so complicated, those are amateurs. It's just biological filtration. The filter is only used to cultivate nitrifying bacteria, and toxic ammoniated substances are decomposed into nontoxic nitrates by nitration (chemical reaction). As long as enough glass rings are placed in the filter (the more, the better, it is best to fill all N layers), because nitrifying bacteria grow in dark rooms and attach to porous substances. The rest, it's all nonsense.

In order to prevent dirt from entering the filter screen, several layers of yarn can be added at the water inlet to keep the dirt out. If you can, don't clean the filter. Those dirty and yellow inside are nitrifying bacteria.

The internal organs of the cylinder and the nitrate produced by transformation are discharged out of the cylinder by changing water.

Question 7: What brand of fish tank filter is good depends on your budget. Jiabao and Risheng are cost-effective, but to be honest, the quality can only be said to be ok. Chuangxing (AT) is better and the price is higher, which is the best among domestic brands. If it succeeds, it will still be Han Yi's. Of course, the price is also very high. Han Yi classic series external filters are all made in China, with good cost performance. I bought it with classic350, 15W for 650 yuan, which is not bad. Regardless of the price, it is of course the third-generation series external filter barrel of Han Yi players, which is the best to use, but the price is more than 3,000 yuan.

Look at your budget and do what you can.

Question 8: Which filter is good for fish tank? The filter above is simple, and the filter below is powerful. If space is limited, you can choose side filters and filters. Plant some aquatic plants in the upper filter pool, such as green radish, LYSIMACHIA christinae and Phyllostachys pubescens. If the water is not changed for one year, the effect will be watertight!

Question 9: What brand of fish tank filter is good? The density is too high and it wastes a lot. Need to strengthen filtration and filter materials. Mud water is generally not because the waste is unclean, but because the waste cannot be metabolized and there are few bacteria. Generally speaking, parrots are kept in bare water tanks. Without sand, bacteria will not attach. It is suggested to reform the filtration system instead of relying solely on the filter. The filter material of the filter is really limited, and such a high density can't meet your needs. If the old players keep this density, most of them do bottom filtering. I don't know your tank, so it's not good to suggest, but try to increase the filter material. In fact, there is no difference between good and bad filters. To put it bluntly, it is a water pump. As long as it is durable, quiet and dynamic, it is the same for any brand. The key is to filter materials, which should be suitable and sufficient. Generally, if it is added later, it is feasible to customize or make a large-area upper filter, or it is also possible to add a waterfall plug-in. If you have money, you can use the outer filter bucket. There is nothing to say.
