The YU-228A is a dual-sponge pneumatic aquarium filter that combines mechanical trapping with biological media chambers for efficient fish tank filtration.
Key Specifications and Features
Design: Double-sponge layout with built-in containers holding biological media balls (typically ~100g to 200g of ceramic/media balls).
Dimensions: Scalable height ranging from approximately 21 cm to 29 cm.
Operation: Requires an external air pump (pneumatic) connected via airline tubing to drive water flow and oxygenation.
Filtration Type: Dual biochemical cotton sponges capture fine debris, while internal media compartments house beneficial nitrifying bacteria to break down harmful waste like ammonia and nitrite.
Setup and Maintenance Tips:
Pre-soak: Soak the sponges in tank water for 5 minutes before first use to help kickstart bacterial colonization.
Cleaning: Always rinse the sponges using room-temperature aquarium water rather than tap water to protect the beneficial bacteria. Never use hot water
