As a DIYer cichlidophile, I'm always on the lookout for aquarium resources beyond the typical pet store and LFS fare. Because I like to tinker with new methods of filtration, I keep my eyes open for new and different bio media.
While looking for some small, floating plastic bio media for a small fluid bed filter that I'm working on, I came across a company in East Tennessee called Smoky Mountain Bio Media. They do business primarily with industrial customers, however they offer media on a much smaller scale for the aquarium hobby. I ordered a gallon of their BioFLO 9 white floater media, which was promptly delivered. Two pieces of the BioFLO 9 are pictured below (far left) with some other bio media for size comparison. I'll write an update once I get the filter up and running.
