Can fish ponds be disinfected when the weather plummets?

The weather plummeted and the fish pond could not be disinfected.

When the weather drops sharply, the immunity of fish in fish ponds will be greatly reduced. At this time, sterilization will destroy the healthy bacterial balance system in the fish, which will lead to the fish getting sick.

Sterilization refers to the process of killing pathogenic bacteria, but it has no effect on other microorganisms including spores, algae and zooplankton.
