GC Tek Biological Media Media Type:AlphaONE (For AlphaONE Filters) and a hands-off auto switchShips directly from the manufacturer, typically in 5 7 business days Filter beads are a floating media. The more buoyancy the beads have, the more effective they are. To increase buoyancy, each bead has been injected with air during manufacturing. This way, the beads stay afloat and stay away from the outlet slots on the bottom laterals, preventing the laterals from being clogged, which would prevent debris from being flushed out of the filter.
