Multi-Stage Biochemical Filtration System

Unlike basic filters, the Bluepet BLH-502 utilizes a specialized two-tier wet/dry filtration method to ensure maximum water purity and beneficial bacteria colonization:

• Dry Filter Layer: The top section houses a dedicated filter sponge designed to trap large debris, uneaten food, and particulate matter before it reaches the biological media.

• Wet Filter Layer: The bottom section acts as the biological powerhouse, featuring a yellow bio sponge alongside porous ceramic rings (bio balls). This combination provides immense surface area to cultivate the beneficial bacteria needed to break down harmful ammonia and nitrites.
