I have a few pieces of japanese mat that was cut from a big piece.. Each time I patted them on the floor, some small "wire-like" pieces came off.. Is this normal?
Not sure if it matters but they were used in my filter a few years back then I took them out and kept them in the store room.. till recently when I plan to change up my filtration media..
