Self-made bottom filter of Feng Shui fish tank

1. The upper circulating filter is placed on the aquarium, and the whole filter pool is exposed outside the aquarium. Water is pumped into the filter tank by submersible pump, and then flows back to the aquarium through the outlet pipe at the bottom of the filter tank, as well as filter cotton, activated carbon and biochemical stones. You can put it in a filter tank. The biggest advantage of the upper filter is that it is easy to clean. When the filter material is polluted, it can be easily taken out for cleaning.

2. The biggest disadvantage is that it is relatively large in size and occupies a relatively large space. Moreover, because there is not enough filter material, the general biological filtration effect is not good. Moreover, in the breeding period of fish, because the water flow is relatively fast and the water absorption capacity of the suction pipe is large, it is easy to suck small fish into the filter. Therefore, it is best not to use it in the fish breeding season. In addition, the upper filter screen is not suitable for aquariums where aquatic plants are planted. The water flow on the upper filter screen will reduce the residence time of carbon dioxide in the aquarium. At the same time, the water flow on the filter screen will also bring a large amount of oxygen in the air into the water, and the oxygen content in the water will increase, which will make algae that like oxygen grow in large numbers and affect the ornamental effect of the aquarium.

3. The bottom cylinder is a glass cylinder placed below the main cylinder, which is generally placed in the bottom cabinet. If space permits, you can also put it where you think it is appropriate. It is connected with the master cylinder through a pipeline and circulates water through a water pump. The cylinder is divided into several compartments by glass, and different filtering materials or equipment can be placed. Different baffles can guide water through the filter material or equipment in a "top-down" or "bottom-up" way.

4. If you are a novice, don't raise expensive fish. If the first fish are not good, they will be destroyed. Keep a few cheap parrots. Silver dragon is one meter smaller. Personally, I think the scenery needs strong filtering. Your bottom filtration should be fine. Can be set appropriately, mainly depending on personal preferences.

5. There is also the change of water. It is certain to change the water in the fish tank. No matter what you filter, the fish tank is full of stagnant water, so you need to add some new water. If your fish tank ecosystem is established and the water quality is stable, you can change the water by three to a quarter in ten days, or when the water becomes turbid, you can also change the water in moderation.

6, tropical fish, the temperature difference of water should be controlled. If you haven't bought fish, put the fish tank in water for a few days, then change the water completely and raise the water first. Raise water first and then buy fish. Explore slowly. Raising fish is like raising children. I wish you and your fish a happy life!
