Drainage Pipe Selection:
Drainage pipe with PVC pipe, according to the size of the fish pond to choose, generally 10 tons of pools with a diameter of 110 mm, 50 tons of pools with a diameter of 160 mm, more than 100 tons to more than one drain. In addition to the sedimentation bin filtration bin in the drain can choose a small diameter, such as 75 mm diameter pipe fittings.
After the pipeline is good, we must lay reinforcing steel mesh, according to the size of the fish pond to choose the appropriate specifications of the rebar, longitudinal and transversal paved into a net, with a good tie wire, the following stone pad up to a certain height, and then you can hit the concrete bedding, the thickness of bedding according to the size of the fish pond to be determined, generally not less than 20 centimeters. The mouth of the pipe should be reserved for a part of the insertion of a good level marking, when playing bedding along the marking of the cut and stick directly, directly to the mouth of the height of the fish pond molding the bottom of the pool and the height of the bottom of the filtration bin. Playing bedding to the mouth of the pipe under the 0.5 centimeters to 1 centimeter after the left (later smear cement), and then began to use red bricks to build cement pools and filtration silo frame. The filtering bin must be able to be operated by a person. Red brick to 1/3, to add a layer of rebar ring, 2/3 to add another layer. Pay attention to reserve the drainage of surface water and circulation pump pipe hole, almost to the top of the buried water inlet pipe and electrical conduit, pay attention to the electrical conduit mouth can not be below the level of the pool water, to prevent electrical leakage. The inlet pipe port is selected in the clear water bin. The high and low walls in the filtration bin are then built later.
After the frame is done, start wiping the cement surface, at least three courses and four layers, the surface layer of cement should be added to cement glue, in order to prevent leakage and seepage. Especially pay attention to the waterproofing of the bottom of the filtering bin, near the pipe fittings should be carefully wiped. After wiping start to build high and low wall, high and low wall of cement surface can only wipe a layer, polishing on the line.
At this point the basic framework of the fish pond is complete, after the cement is completely solidified, you can add the filter media. Put nothing in the sedimentation bin, and put biochemical filter media (bioballs, ceramic rings, coral stone, activated carbon, ammonia-absorbing stone, volcanic stone, bacteria-absorbing house, etc.) in the bin next to it, without filling it up, and leave a space in the center for the insertion of the tube.The space at the bottom of the overhanging wall between this bin and the next bin is filled with biochemical cotton.The next compartment is the filter compartment where the brushes are placed, and the brushes are filled as much as possible. The fresh water compartment contains the germicidal lamp and the circulation pump.The power of the germicidal lamp is calculated according to the body of water, consuming 2 watts per square of water. Circulation pump depends on the flow rate, the basic two to three hours can be circulated through once canThe
After the filter material is installed, insert the pipe can be added to soak the pool. At this point, the cycle of filtration pool has been built, soak the pool to maintain a good water can be put fish.
