Seachem Renew 20L (5.3 gal.) Is ideal 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 well-planted aquaria. It is also beneficial for use in soft-water aquaria where the pH raising property of carbons is not an asset. Renew will remove organics and particulates in the sub-micron range; it will also help control ammonia, phosphates and nitrates. Renew is also quite economical owing to its low up-front cost. 250mL treats up to 160L (40 gallons). Marine and freshwater. This item is a special order item only
