## Summary description

AquaNatura Super Round Hole media filter filler, granules with 25×30 mm round holes supplied in a 20 kg bag. Designed for aquarium and pond filtration systems to provide mechanical support and improve water flow through filter media. Suitable for use in biological and mechanical filter chambers where stable particle capture and water distribution are required.

## Long description

AquaNatura Super Round Hole media filter filler consists of granules with round perforations sized approximately 25×30 mm, supplied in a 20 kg bag. This filter media is designed for use in aquarium and pond filtration systems where stable mechanical support and improved water distribution through the filter bed are required. The round-hole structure promotes even flow and helps maintain consistent contact between water and the media surface, supporting both mechanical retention of debris and biological colonization when used in biofilter chambers.
Advantages
The granules provide uniform water flow and reduced channeling thanks to their round-hole design, which aids in even distribution across the filter bed. The media offers stable particle capture for mechanical filtration while its open internal geometry supports surface area for beneficial microbial growth. Supplied in a 20 kg bag, the product is convenient for stocking larger filter chambers and replacing or topping up existing media without frequent reordering.
Suitable for
Aquarium mechanical and biological filter chambers
Pond filtration systems including multi-stage filters
Large hobby and commercial aquaculture setups needing stable media bulk
Systems requiring improved water distribution and reduced channeling
Key specifications
Granule shape: round-hole perforated media
Approximate hole dimensions: 25×30 mm
Packaging: 20 kg bag
Function: mechanical support and water distribution; suitable for biological colonization
Material characteristics: rigid granules designed for stable packing and flow-through
How to use
Place the AquaNatura Super Round Hole media in the designated filter chamber after rinsing to remove dust from packaging. Arrange the granules to form an even filter bed and avoid excessive compaction that could restrict flow. In biological filters, ensure adequate water flow and oxygenation to support microbial activity on the media surfaces. Replace or top up media as part of routine maintenance when mechanical capture capacity decreases or when signs of clogging appear.
Usage recommendations
Rinse media thoroughly before first use. Monitor flow rates and inspect the filter bed periodically; backwashing (if the filter supports it) or gentle rinsing can restore performance. For systems that rely on biological filtration, allow time for microbial colonization before expecting full biological function.
