Manually remove the floating grasses and rotten waters at any time. Excessive growth of plants in the pool can be removed with a tool, removed, and controlled at a rate below 1/3 of the total amount of aquatic plants. It is also possible to cut some grass roads in the middle of the crab pond so that the crabs can have free passage.
Slowly deepen the pool water and discover that the plants in the pond grow too quickly. The pool water should be deepened so that the grass head does not enter the water surface below 30 cm to inhibit its growth. When water is added, it should be added slowly. It can't be added too much at a time. Let water plants have an adaptive process, otherwise dead grass will happen, which is counterproductive.
For ponds with too many aerobic medicines and plants, if the weather is hot, the air pressure is too low, and when it is difficult to cut the grass temporarily, do not temporarily mow and add new water, so as not to stir the bottom of the pond and allow the dirt to appear. The correct method is to first apply some oxygen-enhancing drugs to supplement the deficiency of dissolved oxygen in the water. After the weather and pressure conditions improve, mow and add new water.
Adjusting the quality of water quality The ponds with “mad long†plants have more rotting and filth. Generally, in the case of heavy rain and artificial excision, water quality will be poor in the short term. In this case, water quality improvers, iodine-rich, quicklime, etc. should be applied. Purify the water in order to clarify the water and kill germs.
