Dual-Hole Water Flow Design

This black semi-circle filter foam features a precision-engineered dual-hole configuration that maximizes water throughput while maintaining optimal filtration surface area. The two strategically placed channels allow water to flow freely through the media, ensuring consistent contact with beneficial bacteria colonies.

  • Dual-channel architecture prevents water bypass
  • Maintains even flow distribution across the entire media surface
  • Reduces dead zones where detritus can accumulate

Perfect Semi-Circle Fit

Designed specifically for half-round filter chambers and sump compartments, this semi-circle profile eliminates the gaps and awkward trimming that round foams require in curved housings. The flat back sits flush against the wall while the curved front matches the chamber contour.

  • Factory-pressed semi-circular shape holds form under compression
  • No cutting or modification needed for half-round sumps
  • Snug fit prevents unfiltered water from channeling around edges

Washable and Reusable

Built from high-density open-cell polyurethane, this foam withstands repeated rinsing and squeezing without breaking down. Simply remove it during your maintenance routine, rinse in old tank water or dechlorinated tap water, and reinstall. The cell structure rebounds fully after cleaning.

  • Open-cell polyurethane resists compression set
  • Retains 90%+ of original porosity after 20+ cleanings
  • Chemically inert — will not leach dyes or additives into aquarium water

Long-Lasting Durability

The black coloration is integral to the foam, not a surface coating, so it will not fade or bleed even after years of continuous submersion. UV-stabilized and resistant to biological degradation, this media maintains its structural integrity for the life of your filtration system.

  • Integral black pigment — no surface dyes to leach
  • UV-stabilized for sumps with lighting exposure
  • Resistant to rot, mold, and bacterial breakdown
  • Expected service life of 3-5 years with regular maintenance
