    Surfactant has low toxicity and irritation, and has mild bactericidal and algal inhibition effect, which can effectively control the over reproduction of algae. However, it will not cause excessive water transparency, and can effectively promote the improvement of water microenvironment. Because the above surfactants have some functional groups of vitamins and amino acids, it is actually observed that they can promote growth. For example, BS-12 not only has good growth promoting effect, but also has good water quality adjustment, bacteriostasis and algae killing function.
