Seachem De-Nitrate
Seachem de-nitrate is an economical, natural, porous material with a pore distribution and geometry that promotes both aerobic nitrification within the first few millimeters of depth and anaerobic denitrification at the core. The material has a high surface area and supports a high density of bacteria. Although de-nitrate has capacity to trap nitrate, this, as with other nitrate retaining materials, such as certain zeolites and synthetic resins, is quite limited and the primary mechanism of nitrate removal is anaerobic.
Seachem Zeolite
Seachem Zeolite™ is a naturally occurring, highly-porous mineral that binds ammonia and heavy metals through an ion exchange mechanism. It has the highest ammonia binding capacity of any available zeolite; ten times higher than some products and twice the capacity of the closest competitor. It won’t deplete calcium in saltwater, and it won’t increase general hardness in freshwater, where the ionic strength is low.
