How to put sand in fish culture feng shui

Coarse sand is suitable for planting grass on it. When pumping water, you can leave some water to prevent fine sand from being pumped away by the pump.

Fish tank bottom sand and landscape beautification;

The bottom sand in the aquarium has both aesthetic and water quality regulation functions, such as coral sand used for marine fish, cichlids in East Africa, silica sand with stable properties suitable for planting aquatic plants, and some large rock sand or Yilan sand that can highlight the brilliance of fish.

1. Coral sand: coral or shell fragments, which have the characteristics of continuously releasing calcium carbonate and can keep the PH value in water in an alkaline state. (Applicable to marine fish, invertebrate marine life, cichlids and crustaceans in the three great lakes of East Africa)

2. Silica sand: mostly imported from the United States and the Netherlands, it is very stable in water, with fine particles and quite ornamental. (Application: fish in soft water, such as cichlids, small yellow grouper, fish produced in rivers and rat fish, are suitable for landscaping of aquatic plants)

3. Yilansha: It is beautiful because of its black and white color, but its particles are uneven, and it is rarely used in ecological tanks (suitable for medium and large fish species).

4. Sink wood: imported from Africa, the Netherlands or Southeast Asia, each with different styles, but before use, it is advisable to determine whether it can sink into water and soak it in advance to remove the color. (Usage: it is mostly used as a landscaping tank for acidic soft water, which can be a hiding place for some small fish)

5. Debris: There are many kinds of rocks with great ornamental value, such as black shale or silicified wood, but it should be washed more before use to remove impurities. (Before use, consider whether it will affect the water quality, and some of them will become spawning grounds for fish spawning on the platform. )

Types of fish tank filtration system:

In the process of aquaculture, water quality is affected by residual bait, biological metabolism and individual death. .. will cause the deterioration of water quality. With the breakthrough of fish culture technology, the design of filtration system has also been innovated, which can be roughly divided into:

1. bottom wave plate filtration: fish tank bottom sand is used as filter material, but the whole cylinder sand must be stirred when cleaning.

2. Sponge biochemical filter: A large number of nitrifying bacteria can be attached to the pores of biochemical cotton, which has the function of stabilizing water quality.

3. Filter in water: Filter gas in water composed of submersible motor and sponge, suitable for small fish tanks.

4. Upper filter screen: low price, easy to clean, and can also be matched with any filter material.

5. Up-drop biochemical filter: using biochemical and physical filtration principles to keep the water quality stable and clean. 6. External drum filter: External filter is beautiful, and now it is mostly used in aquatic plant landscaping ponds. 7. Bottom biochemical filter: It consists of a large number of filtering materials and is suitable for marine fish or soft ecological tanks.
