Renew™ is ideal for use in systems where phosphate released from all activated carbons poses a problem. Renew™ is also less aggressive than carbon, making it well suited for reefs and planted aquaria. It is also beneficial for use in soft water aquaria where the pH-raising property of many carbons is not an asset. Renew™ will remove organics and particulates in the sub-micron range; it will also help control ammonia, nitrates, and phosphates.
Renew™ should be used in exactly the same manner as activated carbon. Use 250 mL for each 120–160 L (30–40 US gallons). Use in a filter bag only. Although Renew™ is clean, it is advisable to rinse before use. It lasts about the same as carbon (4–6 weeks).

A: In planted or reef tanks, it can be advantageous to leave some of the organics in the tank so they are available to fish, plants, or corals. In these situations, a media like Renew allows for control of organics without total depletion as with more aggressive medias. Additionally, Renew will leach no phosphate into the tank at all, which makes it excellent for use in situations where phosphates are being tightly controlled.
