About this item Product 1: FILTRATION: Purigen ranges in color from almost white (cream) to light yellow. Seachem Purigen is not a mixture of ion exchangers or adsorbents, but a unique macro-porous synthetic polymer that removes soluble and insoluble impurities from water. Product 1: SELECTIVITY: Seachem Purigen is an organic filtration resin that works hard to remove nitrogenous compounds and waste produced by fish, corals, and even plants, making your water crystal clear. Product 1: CAPACITY: Being both spherical and macroreticular, Seachem Purigen has microscopic pores that increase its usable surface area to many times that of a purely spherical resin. Product 1: REGENERATION: Once Seachem’s Purigen is exhausted, it can be regenerated with a solution of bleach and water. The bleach will literally “burn off” the organics that have been removed from the tank. Product 2: Rapidly Removes Phosphate And Silicate From Marine And Freshwater Aquaria Product 2: Highly Porous For High Capacity And Bead Shaped For Optimum Water Flow Product 2: Outperforms all competing products Product 2: Not Recommended For Phosphate Based Buffers In Freshwater Aquaria
