Bio Sphere Holders - Pack of 2

These bio sphere holders are designed to keep biological media neatly contained while allowing unrestricted water flow for maximum filtration efficiency.

Sold as a pack of 2, the set holds up to 1 kg or approximately 40 bio spheres, making them ideal for high-capacity biological filtration setups.

The holders are sized to fit CADE media baskets and are compatible with popular bio spheres (Mantis Biosperes pictured. Biomedia not included).

Manufactured from PETG, an aquarium-safe plastic, these holders are durable, water-stable, and suitable for long-term submersion in marine or freshwater aquariums.

Designed for practical use, easy handling, and clean integration into existing sump and filter systems.
