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. This product is sold by volume.
