Product details
Media Cup – Bubble Magus is a rigid acrylic filter media cup designed for use with sock-holder based filtration. It’s made to hold filter floss/sponges (or a combination of media you choose) inside the cup, helping maximize contact between the water and the media before water moves onward. In practical terms, it provides a large open flow area through the cup so water can pass through the floss with minimal unnecessary restriction, which can support consistent media performance in sump and filter sock setups.
Features:
- Rigid acrylic construction for stable, repeatable media placement
- Built to fit a regular 4" and 7" sock holder size range
- Additional vertical flow slots in the cup sides help increase the open flow area
- Base venting plus side slots create a large overall open area across the cup diameter
- Designed to support high-flow passage through filter floss without sealing off the available space
- Can be used with filter floss/sponges or mixed media setups using your chosen media
- Media can be positioned (e.g., with a bottom layer) to help maintain available open space for flow
Specifications:
- Compatibility: Fits regular 4" and 7" sock holder sizes
- Cup length: Approximately 8"
- Tube lip diameter: 4.25"
- Tube diameter: 3.75"
- Flow design: Vertical flow slots plus base venting for an open area of about 99% across the diameter
