Activated carbon isn't one-size-fits-all — the flow rate it's running at and the raw material it's made from both change how well it actually performs. Sicce offers two purpose-built carbons: HyperCarbo High Flow for higher-flow canisters and reactors, and HyperCarbo Cocco for coconut-shell adsorption capacity.
Why Carbon Choice Matters
Standard carbon can lose effectiveness at the higher flow rates canister filters and reactors run, since water simply passes through faster than the carbon can adsorb from it. Material source matters too — coconut-derived carbon is prized in the hobby for its finer pore structure and higher adsorption capacity than coal or wood-based alternatives.
Choosing the Right Carbon
- HyperCarbo High Flow — 3x100g pelleted — designed to keep working effectively even at the higher flow rates canister filters and reactors run.
- HyperCarbo Cocco — 2x150g — activated carbon made from coconut shell rather than coal or wood, prized for its fine pore structure and high adsorption capacity.
How to Use Either
- Rinse before adding to clear carbon dust that would otherwise cloud the tank.
- Replace on a regular schedule — carbon exhausts its adsorption capacity well before it visibly "runs out."
- Match to your specific filter or reactor type — High Flow for canisters and reactors, Cocco where maximum adsorption capacity is the priority.
Sicce HyperCarbo is available at Marine Concept Supply in both formulas — order online or pick up at our shop in Wheeling, IL. Shop HyperCarbo High Flow or HyperCarbo Cocco, and browse more aquarium filtration.
