Easy to replace your old media with our pre-cut sheets ready for drop into the BioSteps. Available in green density, blue density, gray density.

Old style BioSteps used a piece of soft open cell foam as the last section in the BioSteps. This has been replaced with another piece of gray Matala instead. The gray Matala will not clog as quickly as the foam but will still give fine particle filtration.

Dimensions: 12" (bottom) x 16" (sides) x 13.5" (top) x 1.5" thick
