Filtration Problems in Fish Farming? Should the fish filter be left open all the time?

If you want to build a nitrification system, you can add an activated carbon to the filter box, and the biosphere and ceramic ring (not the glass ring) can be spread directly on the bottom of the tank along with the sand you bought. Then add the appropriate nitrifying bacteria.

4. Now you only have filter cotton, you also need to buy biospheres, ceramic rings, activated carbon (activated carbon can't disassemble the net wrapped outside), nitrifying bacteria.

If you are not a professional fish farmer, I suggest that you do not need to think about setting up a nitrification system, but only need to maintain good water quality by raising water and changing it frequently.

How to raise water for water: about three days for about one-third of the water, pay attention not to use the tap water just connected, after the tap water is connected, it is best to put it for two or three days, and then change it for small fish Because tap water contains a lot of chlorine and harmful substances to fish Another is to pay attention to the water temperature control of the water, the new water and the water in the original tank, the water temperature should not be plus or minus 1 degree is the best.

In view of the current situation of more novices, so I will tell you some personal experience, I am more interested in practicality and feasibility, so my opinion may not be standard, if there is no right, I hope you will correct, some of the information and **** on the Internet, the source can not be noted one by one, forgive me.

Novice fish farming, of course, should start with the easy, but no matter how easy it is, you have to give it a good living environment. Many novices will want to buy fish at the beginning, and in the end it will not take a day to die, waste money and kill a small life, imagine that you are a fish, you are so hard because of water quality problems, you look at the people watching you with desperate eyes! Stop!

Barrel filtration. Otherwise, buy a scavenger.

It is feasible to fish <> filter barrels, and the filtration effect is still very good for small fish tanks. Filtration is particularly important for fish tanks, on the one hand, it can adsorb impurities in the water into the filter tank, so that the water becomes clear, on the other hand, nitrifying bacteria can also convert the ammonia nitrogen produced after the decomposition of organic matter, so that it becomes nitrate that is harmless to fish, so as to maintain water quality, which is of great help to the growth of fish.

<> Generally, the fish filter needs to be left open all the time. The filter can filter solid residue in the fish tank, cultivate a large number of beneficial bacteria, etc. Fish tank fish need to pay attention to the breeding density, rather less breeding, not more breeding, otherwise it is easy to get sick and die of water quality, the amount of bait must be strictly quantitative, generally 1-2 times a day as well.

It is recommended to change the water every 3 days, add 1 3 new water each time, follow the wall of the tank, and slowly inject it.

1. Should the fish filter be turned on all the time?

If there are no special circumstances, the filter needs to be left on all the time. The filter can not only play the role of filtering solid residue in the fish tank, but also cultivate a large number of beneficial bacteria, such as nitrifying bacteria, which can decompose harmful substances in the water, making the water clear and of good quality.

2. Precautions for fish tank farming

1. Pay attention to the stocking density, according to the size of the container to breed reasonably, pay attention to rather less breeding, not more breeding.

2. The amount of bait must be strictly quantitative, generally 1-2 times a day for good dismantling, each bait amount needs to be eaten by the fish within 30 minutes, remember not to feed too much bait. Too much bait and too little bait is not good, so you should observe the dynamics of the fish when feeding.

3. Place the fish tank near the window where there is ventilation and sunlight. If humans do not bask in the sun for a long time, it will be harmful to the body. Fish living in a small space fish tank also need sunlight, so the fish tank at home must be placed correctly, not facing away from the sun, preferably facing the light.

4. Although the filtration equipment of the aquarium can filter fish feces, food residues, etc. It is also necessary to clean the fish tank, water furniture and filtration system frequently, and clean up their excrement in time, otherwise it is likely to become a breeding ground for diseases.

5. A large amount of water change will lead to many problems, such as large fluctuations in water quality, collapse of nitrification system, fish colds and other phenomena. Change the water every 3 days, 1 3 to 1 5. When changing the water, do not pour it directly into the tank and impact the fish; It should be injected slowly along the cylinder wall.

6. The difference between day and night temperature travel is large, which will make the fish sick. The change of chain season can also easily lead to fish outbreaks, such as white spot disease, water mildew, protruding eye disease, etc. In early spring and late autumn, pay attention to the temperature difference between the new water and the water in the tank.

If conditions permit, you can use a heating rod as a constant temperature measure. Reduce the temperature difference between morning and evening.

1. Top filtration: top filtration, also called upper filtration, is the most basic filtration method, simple operation, convenient, use the fish tank with a submersible pump to pump the water into the filter material with biochemical cotton, biochemical balls, etc., and then leave it in the fish tank after layer filtration, suitable for all kinds of fish tanks in the wild belt, the filter volume can not be too large, otherwise it will affect the aesthetics of the fish tank.

2. Bottom filtration: as the name suggests, the filter material is at the bottom of the cylinder, generally speaking, the bottom sand, magnetic ring, etc. are put on the filter cleaning plate, and the oxygenated water passes through the gap of the bottom sand, and there are more beneficial bacteria on the bottom sand to reproduce, and the purification effect is obvious. At the same time, it may cause the bottom sand to block the filtration channel, resulting in a short circuit in the water body and the loss of water and fertilizer.

3. Internal filtration; The main thing is to sink the filter device into the water, and the filter material is soaked in water, which is more conducive to the growth of beneficial bacteria and has less noise. The physical filtration effect is poor, so it is more suitable for dry 40 80 cm small and medium-sized fish tanks.

4. External filtration: This kind of filter is generally put into the confessional bottom cabinet of the aquarium, and various filter materials are placed inside, which are connected to the aquarium with pipes, and will not occupy the space of the fish tank.

5. Waterfall filter: Waterfall filter filtration is similar to the original ridge of bottom filtration, mainly using a fish tank pump to send water to the filtration dregs, flowing into the filter material filtration and then flowing into the water, because the purified water flows into the fish tank like a waterfall, so it is called waterfall filtration. This method is simple and easy to clean, but sometimes it is not dry to digest the growth of fine chrysanthemum, said waterfall filtration, the most famous is the place of lucky fish in the supermarket, up and down the river, three three down, forming a cycle.
