TetraTec Replacement Filter Foam BF600/700

TetraTec Replacement Filter Foam BF600/700

The TetraTec Replacement Filter Foam BF600/700 is a premium biological filter medium designed for use in external aquarium filtration systems. It offers an optimal balance of surface area, durability, and microbial support to maintain crystal‑clear water and healthy aquatic life.

Key Features

• Size Compatibility: Specifically engineered for Tetra EX filters with a nominal capacity of 600 L to 700 L. The foam dimensions match the internal chamber, ensuring a snug fit and preventing water bypass.
• High Surface Area: Each piece provides approximately 0.5 m² of active surface per 100 ml volume, creating an extensive habitat for beneficial bacteria that convert ammonia to nitrite and nitrate.
• Durable Construction: Made from a high‑density polyurethane core wrapped in a soft, porous outer layer. This structure resists compression over long periods of use while maintaining its shape.
• Biological Efficiency: The foam’s micro‑porous matrix promotes rapid colonisation by nitrifying bacteria (Nitrosomonas and Nitrobacter). A well‑colonised filter can process up to 10 % of the tank volume per hour, depending on flow rate.
• Easy Replacement: The foam is pre‑cut into standard sizes. Users simply remove the old piece, insert the new one, and reassemble the filter without any additional tools or cleaning steps.

Installation Guide

1. Prepare the Filter: Turn off the power supply and drain a small amount of water to avoid splashing. Remove the existing foam by pulling it out of its slot.
2. Insert New Foam: Align the new BF600/700 piece with the filter chamber’s edges. Gently press until it sits flush against the walls, ensuring no gaps that could allow unfiltered water to pass.
3. Reassemble: Replace any covers or seals that were removed during disassembly. Tighten all screws securely but avoid overtightening, which can damage the foam.
4. Prime the Filter: Run a small volume of clean water through the system for at least 30 minutes to establish bacterial colonies before adding fish.

Maintenance Tips

• Inspect the foam every 4–6 weeks. If it becomes visibly clogged or discolored, replace it immediately to prevent reduced flow and water quality issues.
• Avoid using harsh chemicals or bleach on the foam; these can kill beneficial bacteria. Instead, rinse with plain tap water if necessary.
• Keep the filter chamber clean of debris by gently brushing around the edges before inserting new foam.

Compatibility Summary

Benefits for Aquatic Life

The biological filtration provided by the BF600/700 foam is essential for:

• Ammonia Detoxification: Rapid conversion of toxic ammonia into less harmful nitrite.
• Nitrite Reduction: Further transformation of nitrite into nitrate, which can be safely managed by plants or regular water changes.
• Stable Water Parameters: Consistent bacterial activity helps maintain stable pH and hardness levels, reducing stress on fish and invertebrates.

Environmental Considerations

The foam is recyclable. After its useful life, users can dispose of it responsibly by placing it in a recycling bin designated for polyurethane products. This aligns with Tetra’s commitment to sustainable aquarium care.

Conclusion

Choosing the TetraTec Replacement Filter Foam BF600/700 ensures that your external filter operates at peak biological efficiency, providing a clean and healthy environment for your aquatic inhabitants. Its precise sizing, robust construction, and user‑friendly replacement process make it an indispensable component of any well‑maintained aquarium system.
