Fish pond filtration system in the traditional filtration pond more detailed sedimentation bin h pipe practice

I believe that friends who like to keep fish have almost always encountered such a problem: small and medium-sized fish ponds, traditional filtration tanks sedimentation bin does not seem to work as expected, the sedimentation effect is not very satisfactory, thus affecting the effectiveness of the entire filtration system.

In the design of the fish pond filtration system, most of them only consider the site problem, usually reluctant to expand the volume of the sedimentation bin to the entire filtration system of 40%, that is a pure waste, so the general practice is to do the volume of the sedimentation bin to the filtration system of the 25 to 30%.

          In this way, the flow rate of water from the fish pond to the sedimentation bin through the bottom discharge pipe will be relatively rapid, most of the dirt does not have enough time to settle, naturally, with the water flow directly to the next bin, resulting in the effect of the sedimentation bin is greatly reduced. The "h-pipe" is a plug-in structure, if you need to clean the filter bin, you can replace the "h-pipe" with a straight pipe of the same diameter, as long as the straight pipe exceeds the height of the water surface of the main pool, the main pool and the filter pool will be truncated, and then discharged from the filter bin of the water can be cleaned up the filter bin.

When making the "h-pipe", a breather tube is run on the top side of the tee. Advantages are similarventolinThe principle of the pipeline fluid flow from the breathable tube inhalation of air, air mixed into the fluid after the formation of bubbles, one can increase the dissolved oxygen, the second is the rise of bubbles stirring the water body can promote the precipitation of waste.

The advantages of making the bottom drain into an h-pipe hole into the sedimentation bin include::
(1) Turbulence of the water flow into the sedimentation bin, which facilitates the settling of fish waste and other particles
2) The connection between the main pool and the filter bin can be cut off by pulling out the h-pipe and inserting a 110 pipe instead. The filter bin can be thoroughly cleaned by simply pumping out the filter bin.

3) When you need to leave for a long period of time (e.g., 1 to 2 weeks) for business trips and other reasons, to prevent leaves from clogging the holes in the h-pipe, change a 110 pipe with a tee, and the flow of water into the sedimentation bin will be lateral.

The only disadvantage of the "h-tube" is that the diffusion holes may be clogged by leaves, causing a break in the flow; therefore, the hole in the wall of the tube should not be too small; 25 to 30 mm is appropriate.

Some fishermen think that the pulling bin can be built together with the sedimentation bin, but when draining the bottom water or changing the water in other bins, it is necessary to release part of the water in the sedimentation bin first. Therefore, I suggest that the pulling bin should be separated from the settling bin, so that the settling bin doesn't need to be emptied when draining other bins. It is also advisable to place the draw-off bin next to the sedimentation bin, as the sedimentation bin is the most fouled in a koi pond, so that the pipes are shorter, avoiding the retention of impurities, and do not need to be sealed.
