The grade of carbon you need, at a budget friendly price! The unique activation process ensures maximum DOC removal capability, with a minimal impact on trace element levels. No measurable phosphate or heavy metal levels. Pelletized form prevents packing and enables a higher efficiency per unit weight. Instructions Always rinse with RO / filtered water before use, in order to remove dust from shipping. We recommend 1/2 cup (125ml) of carbon for every 100 gallons of actual water volume. Place the carbon in a nylon filter media bag, and in to an area of consistent water flow (sump baffle / canister filter etc.) or employ full time in a reactor. Change every 4-6 weeks. Some prefer carbon periodically; 24-72 hours every 4-6 weeks. Try it! Unlike some competitors, Reef Crest bulk chemicals are sold by net weight not volume - this ensures a consistent amount of product in any package.Some settling may occur in shipping.
