Description
The CNZ 1.5-Inch Bio-Balls with Sponge Media (100-Pack) combines a high-surface-area plastic ribbed shell with an internal foam sponge insert to provide physical mechanical waste trapping and biological microbial colonization for sumps, pond filters, and wet/dry trickle systems.
Dual-Action Biological & Mechanical Filtration
Maximize filter capacity in your aquarium sump or pond filter. The CNZ 1.5-Inch Bio-Balls with Sponge Media combine durable outer plastic geometry with internal porous foam inserts. Water passing over the open spherical structure traps particulate debris in the sponge core while providing ample surface area for beneficial nitrifying microbes to establish.
Clog-Resistant & Easy Maintenance
Designed for continuous, high-volume water flow, these 1.5-inch bio-balls resist compacting and clogging over time. They are ideal for wet/dry trickle filters where continuous gas exchange and aeration are required. During routine maintenance, simply rinse the bio-balls in displaced tank water to flush away trapped organic debris without disrupting established microbe colonies.
- HIGH SURFACE AREA SPHERICAL DESIGN: Engineered with an intricate 1.5-inch plastic geometric outer shell that provides expansive surface area for nitrifying microbial colonization to support a stable nitrogen cycle.
- INTERNAL BIO-SPONGE INSERT: Each individual bio-ball is packed with a porous foam center sponge that traps fine particulate matter while increasing internal biological surface area.
- Product Specifications: 1.5 Inch in diameter, black in color, approximately 100 per bag
- CLOG-RESISTANT WATER CIRCULATION: Outer plastic rib structure promotes even water distribution and aeration, preventing dead spots and channel bypass in high-flow filtration chambers.
- Compact Package Dimensions: Approximately 12 inches x 10 inches x 3.5 inches when flat for convenient storage
- DURABLE NON-TOXIC PLASTIC: Crafted from lightweight, aquatic-safe plastic that will not degrade, warp, or alter water chemistry in continuously submerged or wet/dry trickle environments.
- VERSATILE 100-COUNT BULK PACK: Provides total coverage for aquarium sumps, wet/dry trickle filters, canister filter baskets, koi pond filter boxes, and hydroponic reservoirs.
