Review on Enhance Your Water Quality with OUFISH Aquarium Bio Balls: Ceramic Biological Filtration Rings for Fish Tanks and Ponds! by Josh Sharp

Revainrating 5 out of 5

High quality bio filter materials

Pros
  • Eco-friendly --- Aquarium filter materials, including bio balls, glass ceramic ring, infrared breathing ring, infrared house, infrared ball, nanohome, etc., 6 kinds of filter material combinations to reproduce the filter effect better. Not easy to damage, no need for frequent replacement, economical and environmentally friendly.
