Review on Filter Balls Aquarium Ceramic Filtration by Ashley Valdez

I bought this filter material to add to the activated charcoal in my bio bags but the material is quite large. The largest material (filter balls) was one inch in diameter and the barrel shaped material was 1/2 inch in diameter. I ended up breaking the material into 1/4 parts and mixed with charcoal. The material worked well. The water stayed clear twice as long as if only charcoal was used. I will definitely buy from this seller again, I will just read carefully and take a much smaller size.
