The dosage should be halved and the application should be done in small amounts multiple times. In most fish ponds, due to the excessive use of chlorine preparations and surfactant products in the early stage, the bottom of the pond becomes compacted and a large amount of toxic and harmful substances accumulate in the lower layer. At this time, the dosage cannot be too high. 


One-time use. Pay attention to the dissolved oxygen in the water body. It is recommended to increase the oxygen level. After breaking the crust, if the dissolved oxygen at the bottom is insufficient, the accumulated sulfites, hydrogen sulfide, and other toxic substances will be released into the water body, causing stress. 


Persist in periodic bottom cleaning. Don't wait until problems occur before carrying out the bottom cleaning. During the summer heat period, bacteria grow and multiply rapidly, so the cleaning cycle should be shortened to once every 4-5 days. 


When using it, adhere to the "potassium hydrogen peroxide compound salt + beneficial microorganisms" mode, and pay attention to the micro-ecological balance of the water body. By leveraging the comprehensive ecological effects of beneficial bacteria and algae, the water body can achieve a micro-ecological balance. 


Avoid using alkaline products simultaneously or consecutively. When using different products to treat the base layer in succession, pay attention to the compatibility restrictions of the products used before and after. Do not follow the trend and use products randomly. After using perchlorate preparations, wait for 2 days before using again.
