The Biotope Sintered Glass Tubes are premium biological filtration media designed for both freshwater and marine aquariums. Crafted from high-quality sintered glass, these tubes provide a large surface area for beneficial bacteria to grow, supporting an effective nitrogen cycle and maintaining optimal water quality. Suitable for canister filters, sumps, or filter reactors, they efficiently process ammonia and nitrites, helping to create a balanced and healthy aquatic environment.
High Surface Area: The sintered glass structure maximizes space for bacterial colonization, enhancing biofiltration efficiency.
Enhances Water Quality: Promotes the nitrogen cycle by converting harmful waste products into less toxic compounds.
Durable and Long-Lasting: Made from premium glass, the tubes resist wear and maintain filtration performance over time.
Easy Integration: Compatible with canister filters, sumps, and filter reactors; simple to add to existing systems.
Safe for Aquatic Life: Suitable for fish, plants, and invertebrates in all aquarium types.
Multiple Sizes Available: Offered in 300 mL and 500 mL to meet different filtration needs.
Rinse thoroughly before use to remove dust or debris.
Position the tubes in canister filters, sumps, or reactors to ensure water flows through and encourages bacterial growth.
Clean periodically to prevent buildup and maintain efficient biofiltration.
Replace only when necessary; the tubes are long-lasting with proper care.
Suitable for both freshwater and saltwater setups.
