Coir Tech Cartridges FAQs
Answers to the questions most commonly asked about our Coir Tech Cartridges.
The Coir Tech ™ cartridges are black because they have been coated in a layer of carbon which is naturally black. Carbon is used as a chemical filter material which removes dyes, odours and impurities.
Coir Tech ™ cartridges are made from coconut fibre, natural latex and carbon.
They are designed to be replaced after 28 days as per the packaging instructions, but the coconut is a strong natural fibre and will last much longer than the 28 days as long as it’s not washed. They are not designed to be cleaned to be repeatedly reused as they are biodegradable and will then need to be replaced.
The Coir Tech ™ cartridges have been extensively tested against the original CF plastic cartridges and perform better in filtration, both in terms of water clarity and water quality. They also have no effect on the aquarium’s natural eco system.
The Coir Tech ™ cartridges can take up to 5-8 years to naturally biodegrade depending on the environment they are in. The hotter and wetter the environment, the quicker they biodegrade. l.
If possible, use a home composting bin to compost the Coir Tech ™ cartridges. If a home compost bin is not available, they can in most cases be put in the general waste bin as this will be used for green energy. Contact your local council for recycling advice.
Submerge the Coir Tech ™ cartridge under water for 5 seconds to expel any trapped air in the coconut fibre before inserting into the Bio CF filter.
This is normal as coconut is made from a natural fibrous material, rinse under water for 5 seconds before inserting into the Bio CF filter. After extensive testing these fibres do not enter into the aquarium itself but are trapped in the Coir Tech ™ cartridge which makes it a great filtration material.
The Coir Tech ™ cartridges will fit all the original CF filters, please visit www.interpet.co.uk to find out how to fit your new Coir Tech ™ cartridges without the need of a conversion kit.
The conversion kits are only there for anyone who wants to upgrade their existing CF to Bio CF. This allows the back Coir Tech ™ cartridge to be removed without getting your fingers wet and also the addition of the Bio Holster on the Bio CF Mini. See how to fit the conversion kit here.
Yes, when using fish medications remove the two Coir Tech™ cartridges as they include activated carbon, which will remove the medicine from the water and reduce it’s effectiveness. The medications will not affect the biological filtration (ceramic rings) so keep these in the Bio CF filter throughout the treatment. 7 days after the final dose of medication, perform a 30% water change and then return the two Coir Tech™ cartridges to the filter. See the individual medicine label for more information.
