First, read the English article below.

To start, you'll want your aquarium completely assembled and filled with everything you want in it, besides the fish. See our articles on setting up freshwater and marine aquariums for more information. Below is a brief checklist of things you'll want to do before getting started — this may not match all aquariums perfectly:  Assemble the aquarium Add substrate Add water Add air stones, air pumps, etc. Add plants, rocks, etc. Add filtration system (and/or protein skimmer) Add heater Your goal in this cycling process is to populate the tank with fish that produce waste but can survive the initial high levels of toxins long enough for the beneficial waste-processing bacteria to grow. Thus, you'll want to pick a variety that is known for being a good cycling fish and start with a small number. Later, once the bacteria have grown, you can slowly add more fish of different types. Below are just a few good choices for cycling fish:  White Clouds Zebra Danios Cherry or Tiger Barbs Pseudotrophius Zebra Banded Gouramis X-ray Tetras Pupfish Most minnows Most guppies When cycling an aquarium with your fish, it's very important not to overfeed them. Though different fish may have different dietary needs, a good rule of thumb is to give food once every other day. Only offer a moderate-sized meal — you don't want any extra food left over when the fish are done eating. This is done for two reasons:  Fish who eat more produce more waste, which can cause the levels of toxins in the tank to rise before the bacteria have a chance to colonize the aquarium. Leftover food will eventually rot, producing toxins on its own. While you're waiting for your tank to cycle, every few days, replace about 10-25% of the tank's water. As with the reduced feeding schedule described above, this is another way of ensuring that toxin levels don't get too high before the bacteria has a chance to grow. If you have a saltwater tank, don't forget to add a suitable amount of marine salt every time you change the water to keep the tank at a proper... 

Now, please write a short abstract for it in Vietnamese. Abstract:
Lắp đặt bể cá và hệ thống lọc. Thả một ít cá dễ nuôi vào bể. Cho cá ăn ít. Thay nước thường xuyên. Sử dụng bộ thử để theo dõi mức độc tố. Dần dần thả thêm cá khi mức độc tố hạ xuống gần đến mức “không”.
