1. Microbial preparations.
A microbial agent is a type of reprimer that uses beneficial microorganisms to improve the substrate. Beneficial microorganisms can decompose organic matter at the bottom of the pond, reduce the content of harmful substances such as ammonia nitrogen, hydrogen sulfide, nitrite, etc., and improve water quality. At the same time, microbial agents can also promote the immunity of aquatic organisms and enhance their disease resistance. Many breeding friends are using: EM bacteria pioneer, increase the content of beneficial microorganisms in the pond, improve the ecological environment of the pond, purify the water quality, and reduce the content of harmful substances.
2. Strong oxidizing agent.
Strong oxidants can quickly oxidize the organic matter at the bottom of the pond and reduce the content of harmful substances. At the same time, oxidants can also increase the dissolved oxygen content of water bodies and promote the respiration and growth of aquatic organisms. When using strong oxidants, it is necessary to spread them evenly in the pond and take care to control the amount and frequency of use so as not to have a negative impact on aquatic life. It can also be used to oxidize and biological bottoming at the same time: double reform pioneer, can improve the pond environment, reduce the content of harmful substances and organic matter, and prevent water quality from deteriorating too quickly.
3. Adsorbents.
The adsorbent can adsorb ammonia nitrogen, hydrogen sulfide and other harmful substances at the bottom of the pond to purify the water quality. Adsorbents can also regulate the condition of the water body and increase the buffering capacity of the water body. If the adsorbent is used too much, it will accumulate at the bottom of the pond and easily lead to the deterioration of the pond environment, so when using, it is necessary to pay attention to controlling the dosage, and if the pond environment deteriorates seriously, it is best to take other measures to change the bottom.
Fourth, quicklime.
Quicklime is a common bottoming agent that can effectively increase the pH value of the bottom of the pond and kill pathogenic bacteria and parasite eggs. Quicklime also neutralizes acids at the bottom of the pond, promoting the decomposition and recycling of organic matter at the bottom. When using quicklime, care needs to be taken to control the amount used so as not to cause excessive impact on aquatic life.
