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.
Sizes: 100 mL, 250 mL, 500 mL, 1 L, 2 L, 4 L
Renew™ should be used in exactly the same manner as activated carbon. Use 250 mL for each 120–160 L (30–40 US gallons). For best results, Renew™ should be placed so as to maximize the flow of water through it. Use in a filter bag such as the Zip Bag™. 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.
