Kolar Labs Crystal Cal Carbon 320g (0.7lb) is a granular activated carbon media designed for aquarium filtration. Use it in fresh, brackish, or saltwater setups to help clear water by adsorbing dissolved organics that can cause cloudiness and unpleasant odors. It’s intended for use in common filter formats (such as filter media bags, cartridges, canisters, reactors, and hang-on filters) where carbon flow-through improves contact with the water.
Features:
- Helps eliminate cloudy water in fresh, brackish and saltwater aquariums, tanks, and ponds
- Removes colors, tannins, odors, and other common organic waste contaminants
- Works as filtration media in reactors, canister filters, intank filters, or hanging filters
- Large granules support good flow in media bags, cartridges, and filters
- Uses a sub-bituminous coal base with an optimized pore structure for adsorption
- Washed and steam-activated, produced with low levels of dust and impurity extractables
- Designed for aquarium use and made to meet Food Chemicals Codex (FCC) standards
- Produced via a phosphate-free process to help avoid adding phosphate to the system
