Desc:Aquatic farmers know that the hardness of the water body is very important, not only for the conversion of organic matter, but also for reducing the toxicity of toxic substances (heavy metals, hydrogen sulfide), but also for the growth and development of algae and prawns. The hardness of water refers to the content of divalent and multivalent metal ions in the water, including calcium, magnesium, iron and so on. Therefore, to maintain the hardness of the water body, it is also a good choice to use feed grade calcium formate to supplement calcium ions.
