Dryden Aqua - Activated Filter Media (AFM) 21kg
A highly engineered product manufactured from a specific glass, processed to obtain the ideal particle size and shape. It is exposed to a 3-step activation process to increase its surface area by up to 300 times for superior absorption and filtration. AFM is self-sterilising, filters particles as small as 4 micron, resists bio-fouling, bio-coagulation and wormhole channelling of unfiltered water and filters 30% more organic contaminants than quartz and sand. Available in 3 grades for optimal filtration. Requires 2/3 of usual sand requirement. Please contact us to discuss quantity required for your filter and a freight quote.
