The Spectrum activated carbon block cartridges treat water by removing the bad taste, odour and appearance associated with chemical and organic pollutants.
Contaminants such as chlorine, chloramine, herbicides, solvents and dyes are all treated along with the removal of organics through absorption. Food grade coconut carbon block with higher efficiency and capacity chlorine, chemical and organic taste, odour and appearance removal.
Spectrum also have available a 0.5 Micron Carbon Block, which is primarily used for Chloramine. Which can be identified with the yellow plastic caps. These are substantially more expensive, and for use in a Koi pond aren't very effective. Due to the 0.5 micron filtration, they block up very quickly and greatly reduce flow.
We recommend running the these 5 micron blocks, with the follow up of a QK Char cartridge, for the ultimate water purification.
Available in four sizes, 10", 10" BB, 20" and 20" BB.
- FDA compliant binders which ensures water does not bypass the carbon. Also peace of mind that nothing is leaching into the water from the binder used.
- WRAS approved cartridge ensuring the highest quality manufacturing technique.
- FDA approved
- High flow capabilities
- High capacity Chlorine removal
- Filters down to 5 micron which optimises continued flow rate. Filtering below this is not simply not efficient in a Koi pond scenario.
Chlorine reduction statistics below has been tested at a Free Chlorine level of 2ppm, typical mains water can have 0.1 - 0.5 ppm so expect these cartridges to last much much longer than figures gives.
A 10" cartridge at a Free Chlorine level of 2ppm, with a flow rate of 3.8 litres per minute will last for 11,000 litres.
A 20" BB cartridge at a Free Chlorine level of 2ppm, with a flow rate of 15.1 litres per minute will last for 100,000 litres.

||Free Chlorine Reduction (Litres @ 2ppm)
The Chlorine level we experience in the shop varies from 0.1ppm to 0.3ppm.
We run the 20" BB cartridges, and will expect to get around 600,000 - 2,000,000 litres of water through them at a Chlorine level of 0.1ppm to 0.3ppm !
