Japanese Matting (Fits BF-6000 models)

Finally, a media that doesn't force the water to run around the outside—the open, tangled structure actually lets the bacteria get fed. I've had it in for two weeks now and the flow through the filter is noticeably steadier than with the solid sheets I was using before.

My BF-6000's been running for three weeks on a single load of this matting, and the water's finally flowing through like it should instead of sneaking around the edges. The tangled fibers hold their shape even after multiple cleanings, which is more than I can say for the last media I tried.

Swapped out my old solid media for this and the water clarity difference showed up within a week. The open tangled structure doesn't choke the flow like the block stuff did, and my bacteria seem way happier for it.
