Sera Crystal Clear Filter MediumSera Crystal Clear is a water-polishing filter pad/medium that clears fine, cloud-causing particles your regular filter media miss — the haze from s ubstrate dust, a bacterial bloom, or a recent rescape. Placed in the filter, it acts as an ultra-fine mechanical stage, trapping the tiny suspended fines that leave water looking less than crystal clear. This is the convenient 12-pack.Simply add a pad to your filter's flow path after the coarser media; it clears the water over the following hours and is then replaced with a fresh pad. A quick, disposable fix for that frustrating post-maintenance haze. Show more
