Greater than one weekAlthough not the cheapest choice in active carbon i belive its by far the best choice and all i will use in my reef system, lowest phosphorus levels of any carbon , spearical shape allows for better flow as well as more surface area also due to spherical shape. Keeps my water spotless and safe for critters, i like to change every 2 weeks as i feel as it still may be working in my 100 gallon its mostly exhausted .

> 3 dayAs with most other Seachem products this one is no different. I am using this in my Fluval 307 canister filter for my 45 gallon freshwater aquarium. I have decided to go with this to save on spending money on the Fluval charcoal inserts. So far I have been pleased with the performance of this product. I am using nylon bags in my filter and I have had no problems.
