## Summary description

Filtration media beads from AquaNatura, model Super Round Hole, sized 25×30 mm supplied in a 0.5 kg pack. Designed as aquarium filter media to provide mechanical support and flow-through surface area for biological colonization. Suitable for use in canister filters, sumps or internal filter housings where spherical media with large through-holes is required.

## Long description

AquaNatura Super Round Hole media filtration beads 25×30 mm in a 0.5 kg pack are spherical filter media designed for aquarium use. Each bead features a large through-hole to encourage water flow while providing a stable surface for biological colonization. These beads are intended for use in canister filters, sumps and internal filter housings where durable, high-flow spherical media is required to support mechanical retention and biological filtration processes.
Advantages
The large central holes in each bead promote uniform water circulation and reduce clogging compared with solid beads. Their rounded shape minimises pressure drop and allows easy rinsing and maintenance. Manufactured from non-toxic, aquarium-safe material, the beads offer a consistent surface area for bacterial communities that break down ammonia and nitrite. The 25×30 mm dimensions balance compact packing density with open flow characteristics for a reliable mix of mechanical and biological performance.
Suitable for
 Canister filters in freshwater and marine aquaria
 Sump filtration systems in reef or planted tanks
 Internal filter housings where spherical high-flow media is preferred
Key specifications
 Bead shape: spherical with large central through-hole
 Individual bead size: approximately 25 × 30 mm
 Package weight: 0.5 kg
 Material: aquarium-safe polymer (non-toxic, durable)
 Function: mechanical support and surface area for biological colonisation
How to use
Rinse beads thoroughly with dechlorinated or tank water before first use to remove any dust from manufacturing. Place the beads into the filter media basket, media bag or the filter chamber ensuring even distribution to maintain consistent flow. Avoid packing beads so tightly that water cannot move freely through the holes; leave enough space for water circulation. Monitor mechanical debris accumulation and clean by gentle rinsing in tank water during regular maintenance to preserve biological colonies.
Usage recommendations
Use the AquaNatura Super Round Hole beads in combination with finer mechanical media upstream to capture large particles before they enter the beads, and consider pairing with biological media of higher surface-area materials if additional nitrifying capacity is required.
