Why does Xiaomi Smart Pet Fountain filter/sponge get worms?

Solution:
The filter element\sponge itself will not grow insects. The eggs are mainly affected by the environment. For example, mosquitoes will lay eggs in the water source at a suitable ambient temperature. Some eggs will also fall into the water with pets and gradually hatch over time. It is recommended to replace or add water every 2-3 days. Rinse the filter element, sponge and other cleaning parts when changing the water; it is recommended to clean it at least once a week (including the water storage bucket, water storage top cover, filter element tank, filter element), and change the water thoroughly. In summer, the cleaning cycle can be appropriately shortened to ensure pets Drink high-quality water.
