1. Many people believe that filter media only serve to purify water quality, but in reality, they act as a habitat for beneficial bacteria.

The larger the surface area of the filter media, the more nitrifying bacteria it can support. A higher population of nitrifying bacteria leads to more effective biological filtration, resulting in clearer water.

2. Our nano-level bacteria-cultivating filter media feature a densely structured microporous system, providing an ideal environment for nitrifying bacteria to thrive. Properly cultivating nitrifying bacteria in the aquarium is essential for maintaining crystal-clear water and a healthy aquatic ecosystem.
