If the water for fish farming becomes muddy, the first thing to do is to strengthen filtration. For the bare cylinder, it is better to place a filter, if there is a filter, but the filtering effect is not good enough, it needs to be replaced, or clean the dirty things on the filter material.
Filtration to improve water quality is gradual, and water change is much faster. The turbidity of water quality is essentially due to too much microbial content in water, which can be discharged by changing water to reduce its density, which is also helpful to improve water quality. Change water must change trapped tap water, through drying to remove chlorine, and then change one third, if possible, it is best to pump water from the bottom, so that residual bait and feces can be removed, but also to inhibit further microbial reproduction.
If there is a good nitrification system in the water body, the number of microorganisms will not be so large, so bacteria culture also has a certain auxiliary effect on improving the turbidity of the water body. Pour nitrifying bacteria into the water, then turn off the light and explode oxygen, as aerobic bacteria, can quickly reproduce to a certain scale, thereby improving the turbid water quality.
The source of turbidity is actually organic matter in the water, including not only fish feces, but also residual bait. If the amount of feeding is too large at ordinary times, the fish can not finish eating, resulting in residual bait falling to the bottom of the water, which will also make the water turbid. Therefore, it is necessary to reduce feeding and stop feeding in a short time, but the time of stopping feeding should not be too long.
