Fish filtration system

The construction of a general ornamental fish pond mainly includes two parts. One is the main part of the koi fish pond, including the basic civil engineering and pipeline layout of the fish pond; the other part is the fish pond water circulation filtration system, which is the key to maintaining good water.

"To raise fish, you need to raise water first, and to raise water, you need to raise bacteria first." This is the hard truth. If you want to keep the water clear, you must have a fish pond filtration system. This is not a difficult task, but for newbies who have just raised koi, it may not be so easy. Today I will share with you some fish pond filtration systems. Simple methods and practices.

1. Simple method of filtration system:

1. Trickle filtration method:

Trickle filtration is an integrated filter. It mainly combines physical filtration and biological filtration in a filter tank. The filter tank is divided into several layers. The upper layer of the filter tank is the physical filter layer. The main filter materials are Cotton, biochemical cotton; and the lower layers will contain various filter materials such as biochemical balls, rattan cotton, glass rings, quartz balls, and bacterial houses. 1). Working principle of trickle filtration:

The water is pumped from the fish pond to the top of the trickle box by a water pump. When the top is full, the water will overflow. The water flow slowly and naturally drips into the drip tank on the first floor. It is evenly distributed everywhere through the drip plate; the water flow drips or flows. Pass through the filter material; then flow into the second layer of trickle tank. A process in which the purified water reaches the third layer at the bottom of the drip filter box and flows directly into the fish pond through the water outlet. When the water flows through, it will increase the contact surface with the air, thereby increasing the amount of dissolved oxygen in the water, providing aerobic bacteria with An ideal living environment. (2) Advantages and disadvantages of trickle filtration:

advantage:

2.1. The aeration effect is significant, and the biological filtration effect is significant;

2.2. Small space occupied. Vertical multi-layer design will occupy a relatively small space.

shortcoming:

2.3. Insufficient physical filtration will not have a good adsorption effect on solid waste, thus affecting the filtration effect.

2.4. There is too little filter material, and the time the water stays on the surface of the filter material is too short, and the water quality cannot be completely purified and restored, and the noise is loud. Because it is exposed to the air, noise will usually occur;

2.5. It affects the appearance. Trickle filtration is arranged vertically, which is difficult to conceal in appearance and will affect the overall appearance. (3) Installation conditions for trickle filtration:

3.1. When installing a fish pond, equipment of different specifications should be configured according to the size of the fish pond. It is best to have a length of 210CM, a width of about 50CM, and a height of about 2 meters.

3.2. The trickle box should be installed higher than the highest water surface of the fish pond and placed on a flat horizontal line so that the water is consistent with the water level and can be placed against the wall;

3.3. It is generally best to have three layers of fish pond trickle filtration. The effect of three layers will be very good. The effect of trickle and flow will not be achieved with two layers. If it is four or five layers, it will be too high. If the height is too high, it will Quarrel.
