Ceramic Rings

Enhance biological filtration in freshwater or saltwater aquariums.

For systems that need additional biological capacity, Waterbox Ceramic Rings provide an ideal foundation for beneficial bacteria to thrive. Each ring features an ultra-porous composition that offers a massive surface area for bacterial colonization, while the open ring shape ensures maximum water flow for efficient, consistent filtration.

Ceramic Rings play a vital role in supporting the nitrogen cycle—converting harmful ammonia and nitrite into the less toxic nitrate—helping maintain pristine water conditions and long-term stability. They are especially beneficial for saltwater fish-only aquariums, reef systems with minimal live rock, and freshwater aquariums where added biological support is needed.

Key Benefits:
• Expands biological filtration capacity for any aquarium system
• Promotes the growth of beneficial nitrifying bacteria
• Helps reduce ammonia, nitrite, and nitrate levels naturally
• Suitable for both freshwater and saltwater aquariums
• Ideal for sumps, canister filters, and media bags

With their durable construction and optimized design, Waterbox Ceramic Rings provide a long-lasting and reliable boost to your aquarium’s filtration performance—helping you maintain a clear, balanced, and healthy aquatic environment.

Directions for Use:
Use as many ceramic rings as your canister, sump chamber, or media bag will allow. Rinse in aquarium or dechlorinated water before placement. Clean gently every 8–12 weeks to remove debris—do not scrub, as this may remove beneficial bacteria.
