Purigen® is a premium synthetic adsorbent that is unlike any other filtration product. It is not a mixture of ion exchangers or adsorbents, but a unique macro-porous synthetic polymer that removes soluble and insoluble impurities from water at a rate and capacity that exceeds all others.

MatrixCarbon™ i s bead shaped for optimal hydrodynamics. This provides maximum water flow and contact with a high density of adsorptive sites without the compacting common to granular activated carbon. It out performs other best grade carbons by at least two-fold when compared for total capacity to remove aquarium organic matter, rate of adsorbtion, and duration of use.

Matrix™ is a highly porous media designed to provide exceptionally efficient biofiltration for single site removal of ammonia, nitrite, and nitrate from freshwater, marine, and reef aquaria. Each liter of Matrix™ provides over 700m² of surface, equivalent to over 170 L ) of typical plastic ball media!

Approximately one and a half years ago, Seachem gave Marine Fish a sample of Matrix™. We started using this product in several systems in our store. In every case we saw a significant drop in the amount of nitrates in these systems. I recommend and use Matrix™ for all saltwater systems

First and foremost, I have to say OH-MY-Gosh...your Purigen® product isawesome! My 72 salt water tank was like pond water: dark, algae ridden, and disgusting. I couldn't see more than 4 inches into the water. After hearing about your product through friends, I decided to try it (after trying so many other products)...by God, it was amazing...it worked to CLEAR my water!...and I mean crystal clear, within 3 days ( it was clear in 2 days but crystal clear in 3)....I can't even tell that there is water in my tank anymore.

de nitrate™ is an excellent product for controlling nitrate at concentrations below 20 ppm. I had nitrate at 140 ppm, did an 80% water change, and began using this product with a regular 10% water change. Nitrate has been at zero ever since.’
