Filter media disks AquaNatura Quartz Polygon L 155×35 mm, 20 pcs per pack

AquaNatura Quartz Polygon L filter media disks are rigid quartz filtration elements measuring 155×35 mm, supplied in packs of 20. Designed for aquarium and pond filtration systems, these disks combine mechanical debris capture with a high-surface-area substrate for biological colonization by nitrifying bacteria. The geometry and size make them compatible with canister filters, filter chambers and modular filter setups that accept polygon-shaped disks of these dimensions.

Advantages

These Quartz Polygon L disks offer a durable quartz construction that resists compression and deformation, ensuring consistent flow paths and long service life compared with soft foam media. Their rigid form maintains open channels for water movement while providing extensive surface area for beneficial bacteria, improving ammonia and nitrite conversion. Being pre-cut to 155×35 mm simplifies installation and replacement in compatible filtration units.

Suitable for

• Canister filters designed for polygon-shaped media
• Modular filter boxes and chambers with 155×35 mm disk slots
• Aquarium and garden pond biological filtration stages
• Systems requiring robust mechanical filtration combined with biological support

Key specifications

• Material: rigid quartz filter media
• Shape: polygon-style disk
• Dimensions: 155 × 35 mm
• Function: mechanical debris capture and biological colonization surface
• Pack quantity: 20 disks per pack

How to use

Install the AquaNatura Quartz Polygon L disks into the filter chamber or canister according to the filter manufacturer's layout, ensuring disks are seated flat and water flows through the media as intended. Rinse disks briefly with dechlorinated water before first use to remove any loose particles from manufacturing. Maintain a typical filter assembly order, placing these disks in stages where they will receive adequate water flow for mechanical trapping and bacterial colonization.

Usage recommendations

Monitor flow and water parameters after installation; allow time for biological colonization and avoid cleaning all disks simultaneously to preserve beneficial bacteria. Replace individual disks when physically damaged or when cleaning no longer restores acceptable flow.
