The Aqua One Ocellaris 138S black sponge is a genuine replacement fine foam insert designed specifically for the Aqua One Ocellaris 850 and 850-UVC external canister filters. It provides dual-action filtration by trapping medium-to-small waste particles while acting as a vital cultivation site for beneficial aerobic bacteria.
Key Specifications & Features
- Material & Density: High-quality fine foam with a 35 ppi (pores per inch) rating.
- Filtration Type: Dual mechanical and biological filtration.
- Pack Size: Usually sold as a 2-pack.
- Compatibility: Made strictly for the Ocellaris 850 and 850-UVC media baskets.
Maintenance & Replacement Cycle
- Routine Cleaning: During regular tank maintenance, gently rinse the sponge in a container of removed aquarium water to clear trapped debris. Never use tap water, as chlorine will destroy the beneficial bacterial colony.
- Replacement Timeline: Depending on your fish stocking levels, manufacturers recommend completely replacing the sponge every 8 to 16 weeks (or up to 4–6 months if it maintains its structural integrity).
- Flow Rate Warning: Because 35 ppi is a relatively fine foam, it will eventually clog and reduce your canister filter's water flow. A drop in flow rate signals that the sponge needs an immediate rinse or replacement.
