Some suggestions for the construction of a fish pond filtration system (traditional filter pond)

1. The volume of the filter bin or filter tank is 1/5~1/3 of the koi pond.

The larger the filter tank area, the better the filtration.

2. If you want to add tap water or groundwater to the koi pond, you should put the new water into a filter tank, which will soften the water and reduce the harmful effects of residual chlorine. However, it is better to build a separate sun pond to prevent the tap water from killing the beneficial bacteria in the filter tank.

3, sedimentation bin outlet to add a valve, the plug tube will be loosened over time, no valve will leak.

4. A larger and deeper sedimentation bin will relieve the pressure on physical biochemistry.

5, brush warehouse recommended rattan cotton, brush is suitable for large pools, there is no sufficient number of brushes is equivalent to the furnishings, small pools brush filtration effect does not work.

6, biochemical filtration with ceramic ring, biochemical ball, activated carbon, ammonia-absorbing stone, coral stone, volcanic stone, etc., the overflow ceramic ring is the king, the best cost-effective, drip flow using biochemical ball.

7, biochemical silo must be pre-placed gas head, preferably gas plate, 20cm of the kind of large gas plate, aeration effect is good, nitrifying bacteria need more oxygen than fish. So as long as the gas pump can support, the more the gas plate the more decentralized the better.

8, because the decomposition of biochemical bacteria need oxygen, so the filter tank must be configured to increase the dissolved oxygen in the water ventilator. Commonly used air compressor will air directly into the water, there are also used to add pure oxygen. Outdoor pool sunlight exposure is strong, you can use germicidal lamps to kill excessive green algae in the water. If necessary, you can use the shade device to cover about 1/3 of the fish pool to prevent ultraviolet light on the pool water and fish color, commonly used shade cloth or rubber wave board.

9, clear water warehouse put sterilization lamp, can effectively pre-release germs and outdoor pool green algae outbreak, but do not recommend often open; no green algae should be installed sterilization lamps, in case the need is not likely to cause the death of the fish, so a group of preparation is still necessary.

10, the bottom of the main pool discharge to the sedimentation bin pipeline to be higher than the bottom of the sedimentation bin, depending on the depth of water to determine how much higher, otherwise it is not conducive to sedimentation. Surface water pipe connected to the middle of the sedimentation bin, in the bottom out of the upper go water, this is the principle.

11. The silos, including the main pool, repair the bottom of the pot, which is conducive to sedimentation.

12, more than 2 tons of fish pool is recommended to use 50 w circulation pump, more than 10 tons with 75 w circulation pump, ordinary fish store pumps do a few tons of pool filtration is basically a delusion.

13, the bottom of the main pool pot should be made of flying disk, to facilitate the collection of fish poop, if the density is large, the flying disk on the 20cm air disk, the flow of water and fish poop precipitation to help a lot.

14, between the bins turn over the water board can be used to turn over the water pipe instead, but according to the current use of the effect, turn over the water board is more conducive to avoiding the dead water area, it is recommended to use.

15, sedimentation tank in the koi pond filtration system in the importance of: koi pond filtration system is mostly used in the overflow filtration tank, the first level of filtration unit is designed for solid-liquid separation unit, that is, the fish feces and other solid wastes will be precipitated, and then separated in time to go out, so as to greatly reduce the load on the biochemical unit, so that the water quality can achieve a better biochemical purification.
