What I wonder about is, pumice or Matrix has small pores. After awhile, it appears to me that the pores are all covered with bio film. Doesn't that nullify the effectiveness of the pores? I could imagine that Matrix is effective when new and clean. But, what about 3 months from now? In three months, wouldn't sponges, lava rock, plastic hair curlers be just as effective?
