Welcome to the Bio-CF Filter & Coir Tech™ FAQ page! Whether you’re transitioning from CF filters, exploring our new eco-friendly filtration system, or looking for maintenance tips, we’ve got you covered. Below, you’ll find answers to the most common questions about the Bio-CF range, Coir Tech™ cartridges, and how to get the best performance from your aquarium filter
The Bio-CF filters feature an upgraded, eco-friendly filtration system using biodegradable Coir Tech™ cartridges. They provide advanced filtration, improved water clarity, and a more sustainable alternative to traditional filter cartridges.
Yes! The new Coir Tech™ cartridges are designed to fit seamlessly into existing CF filters, so you can continue using your current system without any modifications.
No, you can use the Coir Tech™ cartridges without a conversion kit. However, if you prefer a cleaner and more convenient filter change process, we offer a Bio-CF Conversion Kit to make maintenance even easier.
Yes, Bio-CF filters function similarly to CF filters but with improved performance. The 5-stage filtration system ensures crystal-clear water and a healthier aquatic environment.
When first inserting The Coir Tech Cartridge into the Bio-CF Filter, natural tannins and flavonoids from the coconut coir may be released into the water, causing a temporary brownish discolouration in very rare cases. These compounds are completely fish-safe and provide beneficial antioxidant and anti-inflammatory properties.
The discolouration is most noticeable within the first 48 hours, but the activated carbon in the Bio-CF Filter will remove most of it over time. If you want to speed up the process, performing a partial water change can help clear the water more quickly. Additionally, the tannins act as a natural algae inhibitor, making them beneficial for maintaining a cleaner aquarium environment..
Yes! The Coir Tech™ cartridges are made from natural coconut coir, making them 100% plastic-free and biodegradable, reducing environmental impact.
For optimal performance, replace the Coir Tech™ cartridge once a month. We offer convenient 1-month and 3-month service packs to make maintenance easy.
Yes! We have an updated installation video on our website demonstrating how to use Coir Tech™ cartridges with or without the Bio-CF Conversion Kit.

The Bio-CF filter is designed to have an overflow system. The overflow does not signify that the filter is excessively dirty but is the correct functioning of the system.
Carry out your usual monthly maintenance and change the cartridge every 28 days for optimal performance.
If you have a lot of fish and/or you feed a lot, it would be worth checking the cartridge slightly more frequently.
