Filtration Media AquaNatura Quartz Hollow Ball 12–14 mm, 0.5 kg

AquaNatura Quartz Hollow Ball filtration media consists of hollow quartz spheres sized 12–14 mm supplied in a 0.5 kg pack. The product is engineered to support both mechanical and biological filtration in aquariums and garden ponds. Each sphere's hollow, flow-through structure provides increased surface area for beneficial bacterial colonization while allowing debris and fine particles to be trapped in the filter system. These inert quartz balls are compatible with common filtration housings such as canister filters, filter boxes and bio-media chambers, and are intended for use as a stable, long-lasting filtration substrate.

Advantages

The AquaNatura Quartz Hollow Ball offers a combination of mechanical particle retention and a porous surface suitable for biofilm growth without altering water chemistry. Its uniform 12–14 mm size ensures predictable flow and packing density inside media baskets or cartridges, and the hollow construction increases internal surface area compared with solid beads of the same size. Being made of inert quartz, the spheres resist degradation and leaching, making them appropriate for freshwater and many pond applications where maintaining stable water parameters is important.

Suitable for

• Canister filters used in aquariums
• Filter boxes and sumps with media chambers
• Garden pond filtration systems
• Biological filtration where surface area for bacteria is required

Key specifications

• Material: inert quartz
• Form: hollow spherical beads
• Bead size: 12–14 mm diameter
• Pack weight: 0.5 kg
• Function: mechanical and biological filtration

How to use

Rinse the AquaNatura Quartz Hollow Ball media under running water before first use to remove any fine dust from manufacturing and packaging. Place the beads into the designated media basket, cartridge or chamber; ensure even packing that allows water to flow through the hollow cores and between beads. Use the media together with mechanical filter pads or sponges for optimal particle capture upstream and with additional biological media if higher processing capacity is required. Replace or clean according to observed performance—gentle rinsing in aquarium water during routine maintenance preserves beneficial bacteria while removing trapped debris.

Usage recommendations

For best results, combine the Quartz Hollow Ball media with a coarse mechanical pre-filter to reduce clogging, and avoid aggressive cleaning that would remove colonized bacteria. Monitor flow rates after installation—if flow is significantly reduced, perform a controlled rinse in tank or pond water. The media is suitable for freshwater aquariums and many garden pond setups; check compatibility for specialist systems (e.g., saltwater or heavily planted tanks) before prolonged use.
