Bacteria and Light
What is the relationship between light and bacteria?
What is the relationship between light and bacteria?
Light is not only unnecessary for the growth of the beneficial bacteria, which improve water quality, but light will inhibit the growth of nitrifiers, particularly Nitrobacter. Biological filters should be kept in the dark. Ultraviolet light is used to kill bacteria. The toxicity of the ultraviolet is a function of the intensity and the duration of the exposure.
