Fish pond circulating filtration tank construction process (I)

       Many fish friends in the fish pond to do civil construction on the construction of the filtration pool, pre-conception is also quite good, the pool is built but found that a variety of problems ensue: filtration is not complete, dirt can not get out, the flow is not enough, leakage and so on. In order for you to understand more about the fish pond filtration system, so that you fish more easily, today we share the specific process and some of the details of the construction of the fish pond circulation filtration pool.

I. Determining location

      As we all know, "mountain hosts people, water hosts wealth". Choose a good location, not only can make the fish pond looks more coordinated with the whole building, but also can gather wealth. Of course, if you have the conditions to find a more professional person to choose the right location, not because of a momentary obsession, resulting in future regrets.

II. Determining size

       After choosing the location, you have to design the size and shape of the pond according to the actual situation, the size is based on the actual terrain and the size and number of Koi you need, it is better to be bigger, so that you don't want to raise big Koi in the future but because of the size of the pond is limited. The shape will be according to your personal preference and aesthetics.Try not to design a rockery or other original landscape in the fishpond, as this is not good for koi keeping. The depth of the fish pond is recommended to be more than one meter, and a little deeper in the north for wintering.

III. Design

       Designing the fish pond to consider the ratio of the filter bin to the fish pond, theThe general capacity of the filter bin should be 1/5 to 1/3 of the total water body.It is best to design it in a corner of the fish pond or in a location that is a little better hidden, and also take into account issues such as future cleanup. The general filtration bins are designed with high and low walls and are divided into four bins, with two ground walls and one overhanging wall. The ground wall is 20 centimeters lower than the edge of the pool, and the hanging wall is 20 centimeters from the bottom of the pool. Having designed the size and shape of the pool, you can then calculate the materials required.

       The materials needed in the preliminary stage of building a fish pond are: concrete (for laying a bedding layer), reinforcing bars (choose the right ones according to the size of the fish pond), red bricks (hard ones, that is, the ones that are burned with a high fire), cement (with a high grade), sand, cement glue, PVC drainage pipe and supporting fittings, PE inlet pipe and supporting fittings, double-core electrical wires, tiles (optional), etc.Buy a good material can be started, if the drainage system allows, filtration pool can be made into the best semi-underground, that is, the depth of the underground depth of the entire pool of 2 / 3 to 3 / 4, so as to maintain the stability of the temperature of the pool water, but also to prevent the foreign matter scraped into the fish pool.

       Excavate the fish pond according to the design depth, it should be noted that the depth of undercutting should be 25-30 centimeters more than the designed depth of the fish pond, because the bedding should be played under the fish pond. After digging, first level the ground and tamp it, then dig a drainage pipe trench from the center of the fish pond to the center of the sedimentation bin, dig a drainage pipe trench from the center of the clear water bin to the center of the sedimentation bin (filter bin drainage), and then dig another drainage pipe trench from the center of the sedimentation bin to the drainage well (or drainage ditch, etc.) (main drainage). It is better to keep a straight line between the filtering bin drainage and the main drainage so that the drainage is smooth. Lower the pipe and bury it, taking care to keep the mouth of the filtration bin pipe slightly lower than the mouth of the pipe in the center of the pool.

      Some of you may ask why the pipes are buried underground instead of being driven into the bedding, wouldn't that be better protection for the pipes?

      The most important thing to consider here is the strength of the bedding, it is not recommended to hit in the bedding, that invariably reduces the thickness of the bedding.
