There is an aquarium at home. How to make a swamp filter?

Amphibians, sunlight is the energy source for the growth of emergent plants. The stronger the sunlight, the stronger the water purification ability of emergent plants. Therefore, the best range of swamp filtration is outdoor full sunshine. Swamp filtration is not new. Mother Nature has used this technology for hundreds of millions of years. We call it aquifer, wetland or swamp. Constructed wetland is also the most economical and ecological sewage treatment method at present. Marsh filtration is equivalent to miniature constructed wetland. No gravel over 30 cm is needed. If it is built too deep, you can build an overhead floor or a sedimentation tank, so that the water flow will be more uniform. The reason why the gravel is less than 30 cm, after a lot of experiments, will not get better water quality, but will only increase the cost.

Marsh filtration needs strong light. Light is the most important external factor of the whole system, and the swamp is an anoxic warehouse. If there is no emergency plant to continuously deliver oxygen to the swamp through photosynthesis, the swamp will become a veritable "biogas digester" and endanger the health of fish. It is really not recommended to make swamp filters indoors. Waterscape Garden needs 10%- 15% pond area, and koi fish Fish Pond needs 20%-30% pond area. (Note that this is for the pond). Please do not apply this formula to small water bodies such as fish tanks and turnover boxes, otherwise the promised effect will not be achieved. The required area depends on the feeding amount and cannot be generalized. No one can predict how much load their filtration can achieve. Both of them are filtered first, and then the feeding amount is adjusted according to the filtering effect.

Please use pebbles about 8mm, also called floor heating bean stone. The size range of stone is 5-15 mm. For a large swamp, it can be slightly larger, and for a small swamp, it can be slightly smaller (which will increase the filtering effect and blocking speed). After putting down a jackfruit, the water became turbid again. Four buckets of water were changed, and a drying platform was built with PVC pipes. The water level in the swamp is too high, and I'm not very satisfied. I'm going to put another 30 Jin of stone down tonight, and I don't want to see the water above the surface of the stone ... then I'll add garlic, aloe, chlorophytum and Juncus. Do you want to fertilize so many kinds of crops, or do you want to raise a vat to do it?

The excrement of soft-shelled turtle causes nitrite to be produced in the water, but nitrifying bacteria have already formed in the water, which will remove nitrite. However, fish farmers all know that it is impossible to nitrify all the excrement, and then there is a big problem that organic matter (also called fertilizer water) depends on plants. The excreta and organic matter in the water will be pumped into the swamp by the water pump, and then the plants will fully absorb nutrients and circulate in turn, which will greatly improve the convenience and efficiency compared with the ordinary filtration system. Even the water will be pumped away by the pump, flow into the bottom of the swamp at high speed through the pipeline, and then be discharged evenly through the dropper. In the process of flowing upward (downward) through gravel/sand, water gradually slows down and impurities form precipitation. Water seeps from the bottom and flows into the water tank through the outlet pipe, forming a filtration cycle.
