Fluval Edge Carbon Renewal Sachet (3 Pack)
$14.95 inc GST
Carbon is the most common chemical filter media used in aquariums and works by binding impurities to its surface as water flows through the filter. Carbon, along with other chemical media, will eventually become saturated and should be replaced every month or so under normal conditions, or immediately if used for an isolated case (i.e. removing residual medication or clearing discoloured water). Fluval manufactures granulated Activated Carbon, which offers a greater surface area for pollutant absorption versus extruded pellet carbons. It is also made with bituminous coal – the best possible raw ingredient for water filtration.
