What fish to raise clean, how to raise fish clean

Methods: 1. The most important thing is to have a set of effective ecological filtration system, including mechanical filtration and biological filtration. Conventional mechanical filtration can only remove solid contaminants, and there are still large amounts of organic matter dissolved in water, such as egg whites, which cannot be filtered out of Pissen, and can only be completed by biological filtration systems.

2. The filtration capacity of the filter should be large enough. The filtration capacity of the filter is expressed in liters per hour. To filter the water, it is generally required to have 4 to 7 filtration cycles, specifically, if the water in the fish tank and aquarium is 200 liters, it is necessary to have a filter of 800 to 1500 liters per hour.

3. The number of fish and the amount of bait should be moderate, the honey of the fish is too large, and the feeding of bait is too much, which is equivalent to increasing the amount of pollution.

4. There are some inferior bait in the market, in order to increase the appearance of the pigment burning mu, the pigment in the bait dissolves into the water when feeding, so that the water becomes colored, if this situation occurs, the bait should be replaced to make the bottom solution.

5. Aquatic plants are also a good helper for purifying water bodies, try to raise as many aquatic plants as possible, so that the entire aquarium becomes a small ecological paradise, and the water body will naturally become very clear.

6. Put scavengers and moss shrimp in the tank, they can remove the dirt and algae attached to the tank wall, so that the tank wall is clear.

1) tap water: tap water is the domestic water used in our daily life, it is convenient and easy to obtain, it has undergone certain technical treatment, it is the best breeding water for freshwater ornamental fish. Tap water is a disinfected water source, and the water contains too many chloride ions to be used directly for fish farming.

Generally, the cooling method is adopted, and the tap water is placed in an open-air ventilated place, with the help of air circulation and sunlight, the residual chlorine in the water is volatilized, and the amount of dissolved oxygen in the water is increased at the same time. The cooling time is more than 24 hours in summer, more than 48 hours in spring and autumn, and longer in winter. In addition, chemical treatment can also be used, that is, baking soda (sodium thiosulfate) is used to neutralize the chlorine in the water, generally 2-3 grams per cubic meter of water or 5-6 grains in 10 liters of water.

When baking soda is used in excess or in hot weather, the water quality often deteriorates white, so special attention should be taken.

2) Well water: Well water belongs to groundwater, the water quality is hard, and the water temperature is constant. Well water needs to be exposed to the sun for more than 12 hours before use, so that the water temperature is balanced with the surface water temperature, and at the same time increase the amount of dissolved oxygen in the water.

3) River water: natural water, soft but turbid. Before use, the sediment should be purified or filtered in a reservoir before use. The river water contains many natural baits that can make the color of aquarium fish more natural and bright.

Fish can be raised with chemical fertilizers, which are mainly used to cultivate plankton in the water. Since there is generally no shortage of potassium in fish farming waters, the chemical fertilizers commonly used in fish farming production are mainly nitrogen and phosphorus.

1. Nitrogen fertilizers:

Nitrogen is one of the main nutrients of plankton in water, which can increase the intensity of photosynthesis, accelerate the reproduction of plankton, and increase the yield of plankton. Nitrogen fertilizers commonly used in production mainly include urea, ammonium bicarbonate, ammonia, ammonium sulfate, ammonium nitrate, ammonium chloride, etc., except for ammonia, all of which are white crystals, soluble in water, hygroscopic, and are all sexual fertilizers.

2. Phosphate fertilizers:

Phosphorus is an indispensable element for the growth and reproduction of plankton, and the application of phosphorus fertilizer can not only meet the needs of plankton mass reproduction, but also accelerate the reproduction of nitrogen fixation and nitrification in water, promote the circulation of nitrogen, and increase the natural bait in water. There are two kinds of commonly used phosphate fertilizers, namely superphosphate and heavy superphosphate, which contain phosphorus that are easily soluble in water to generate phosphate ions, which can be quickly absorbed and utilized by plankton after being applied to water, but there is also a part of phosphorus that will be adsorbed by water droplets and sludge, some generate insoluble salts, and some are gradually released for biological use, and there is still a certain fertilizer effect within 2-3 years of fertilization.

Hello, use phosphate fertilizer, ammonia fertilizer, potassium fertilizer to raise fish. Fertilization promotes phytoplankton growth and provides sufficient food for fish. Similar to crop fertilization, nitrogen, phosphorus, and potassium must be properly matched.

Nitrogen fertilizers are mainly urea, ammonium sulfide, ammonium nitrate and ammonium carbonate, among which urea has the highest nitrogen content, while ammonium carbonate is the cheapest, and has a fast effect and high utilization rate.

In the early stage of breeding, due to the large potassium content of the water body, only ammonia and phosphate fertilizers can be applied. Urea and superphosphate are applied in a ratio of l:2.

If ammonium carbonate is applied, the ratio to its superphosphate should be 2:1. A certain proportion of potassium fertilizer should be applied in the middle and late stages of breeding, and the percentage of ammonium carbonate, superphosphate and potassium chloride is 70:

22:8。Nitrogen fertilizers are mainly urea, ammonium sulfide, ammonium nitrate and ammonium carbonate, among which urea has the highest nitrogen content, while ammonium carbonate is the cheapest, and the effect is fast, the utilization rate is high, and the effect is very good.

Due to the large water surface of the reservoir and the large fertilizer of the farm, the fertilizer can not meet the demand of fish bait, so it must be mainly applied with chemical fertilizer, which has a fast effect and low cost, and the input-output ratio is about l:2.

Hello dear, you can refer to the above content, combined with the actual situation to choose the corresponding fertilizer to raise fish.
