Activated Carbon 1kg

This one-kilogram bag of granular activated carbon is a cost-efficient option for large aquariums, sump filtration systems, and fishrooms operating multiple tanks. Activated carbon's microporous structure adsorbs dissolved organics, tannins, odours, chlorine, and medication residues from the water column, delivering and maintaining optical clarity. The 1kg quantity provides enough media for several filter changes or to fill multiple media bags simultaneously. As with all activated carbon, effectiveness decreases over approximately four weeks as adsorption sites become saturated — at which point the media should be discarded rather than regenerated. Buying in bulk reduces the cost per filtration cycle significantly for high-maintenance systems.
