Renew™ is an effective and economical replacement for activated carbon. While Renew™ is capable of organic removal and sub-micron filtration, it is less aggressive than carbon. It will not alter pH, remove trace elements, or release phosphates. It is suited for the reef or planted aquaria where aggressive chemical action may be a problem. A 250 mL bottle of Renew treats up to 40 gallons for several weeks. Marine or freshwater use.

DIRECTIONS: Renew should be used in exactly the same manner as activated carbon. Use 250 mL for each 30-40 gallons. Use in a filter bag only. Although Renew is clean, it is advisable to rinse before use. Renew will remove organics and particulates in the sub-micron range; it will also help control ammonia, nitrates, and phosphates. It lasts about the same as carbon (4-6 weeks).
