Before first use, rinse under a stream of fresh water. Each 500g of Carbonīt-P is suited to efficiently filtering 450 US gallons (1,703 L) of water. The method in which Carbonīt-P is employed will dictate the reaction time with the water and consequently, the rate at which organic material will be extracted; therefore, the greater the reaction time between carbon pellets and water, the faster this process will occur. In all cases,
the use of a mechanical pre-filter to remove particulate organic material from water before its interaction with this media will prolong effectiveness. Follow the guidelines for media use below; Carbonīt-P may be removed before reaching the maximum recommended filtering time if more than one use is desired. Hobbyists may choose to employ Carbonīt-P for 1 - 2 hours each day throughout 1 month to help improve water quality. If used in this fashion, Carbonīt-P should be discarded and replaced after each month. In high-nutrient aquaria, replace after 24 hours of total use; placement in lower-nutrient aquaria may be extended up to 48 hours of total use.
Canister filtration: Load carbon into the filter cartridge as directed by the filter manufacturer. Slowing the flow of water through the filter may be required to obtain maximum effectiveness of carbon.
Passive filtration: Place Carbonīt-P loosely in an 800μm mesh filter bag and locate it in an area of low- to medium-flow. Turning the bag over once during usage will serve to shift the carbon particles and increases the effectiveness of this method.
