Seachem Renew™ Filter Media is an effective and economical replacement for activated carbon.
While Renew™ is capable of organic removal and sub-micron filtration, it is less aggressive
than carbon. It will not alter pH, remove trace elements, or release phosphates. It is
suited for the reef or planted aquaria where aggressive chemical action may be a problem. A
250 mL bottle of Renew™ treats up to 40 gallons for several months. Marine or freshwater use.

Seachem SeaGel
Seachem SeaGel™ Filter Media is an efficient blend of MatrixCarbon™ and PhosGuard™. SeaGel™ removes organic and color impurities, phosphates, silicates, toxic metals and acids. Both components are bead shaped for optimum water flow characteristics. SeaGel™ is ideal for reef and marine aquarium use, particularly for algae control. It may also be used in freshwater that is not phosphate buffered. A 250 mL bottle will treat 40-60 gallons for 3 to 4 months. Marine or freshwater use.

Seachem MatrixCarbon
Seachem MatrixCarbon™ Filter Media is a truly unique activated carbon, 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. MatrixCarbon™ has a very low ash content as indicated by its minimal impact on pH. Even when added to distilled water, it does not raise pH above 7.0. While all carbons contain phosphate, regardless of false claims to the contrary, MatrixCarbon™ has the lowest leachable phosphate content of all major carbon brands tested. 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. 250 mL will easily treat 100 gallons for several months. It is very clean and nearly dust free. The 100 mL bag size will fit any filter on the market and treats over 40 gallons. Marine or freshwater use.

Seachem HyperSorb
Seachem HyperSorb™ Filter Media is a synthetic adsorbent that outperforms all other blended
synthetic media. It has exceptional organic removal capacity, stabilizes the ionic balance,
and helps to control ammonia, nitrite, and nitrate. Exhaustion is indicated by discoloration.
It can be regenerated easily with household bleach. It is available in convenient 100 mL
bags that treat up to 30 gallons and larger sizes. Marine or freshwater use.

Seachem HyperSorb 1L - $29.99
Seachem Purigen
Seachem Purigen™ Filter Media 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, even HyperSorb™, by over 500%. Purigen™;
removes protiens, nitrites and nitrates, ammonia, and a broad spectrum of organics, yet its
impact on trace elements is minimal. It significantly raises redox. It polishes water to
unparalleled clarity. Like HyperSorb™, Purigen™ darkens progressively as it exhausts, and
is easily renewed by treating with household bleach. A 100 mL bag of Purigen™ purifies and
polishes up to 100 gallons of water for up to six months. Purigen™ is designed for both
marine and freshwater use.

Seachem Purigen 1L - $39.99
Seachem CupriSorb
Seachem CupriSorb™ Filter Media is a powerful adsorbent of copper and heavy metals. It
rapidly removes all types of copper, remaining effective until it turns a deep blue-black
color. When in continuous use, it gradually pulls out precipitated copper and permits invertebrate culture in tanks previously treated with copper. A 100 mL bag is adequate for up to 60 gallons and removes over 3,000 mg of copper or 12 ppm in 60 gallons. It may be regenerated repeatedly. Marine or freshwater use.

Seachem CupriSorb 1L - $39.99
Seachem PhosGuard
Seachem PhosGuard™ Filter Media is a high capacity and high efficiency filtration product for removing phosphates and silicates from marine or fresh water aquaria. Unlike competing products, PhosGuard™ is bead-shaped for optimum flow characteristics and has an exceptional porosity for enhanced capacity. PhosGuard™ has a working capacity to remove 20 to 60 mg/L phosphate in 100 gallons with a similar impact on silicates. It may be used continuously or intermittently, and will not release removed phosphate. PhosGuard™ will cause a decline in hair algae and enhance coral growth. Each liter treats up to 300 gallons. Marine or freshwater use.
Seachem PhosGuard 250ml - $5.99
Seachem PhosGuard 1L - $13.99
Seachem PhosGuard 2L - $23.99
Seachem PhosGuard 4L - $37.99
Seachem PhosGuard 20L - $179.99
Seachem de*nitrate
Seachem de*nitrate™ Filter Media is a high porosity filtration product for the removal and control of nitrate in marine and freshwater aquaria by anaerobic denitrification. It is a porous inorganic solid about 4 mm in diameter. It does not require a special denitrifying filter or special culture feedings. It is also helpful in controlling nitrite and ammonia. The surface area characteristics of de*nitrate™ are similar to Matrix™, making de*nitrate™ an effective support for the biological filter. Each liter treats up to 100 gallons. Marine or fresh water use.
Seachem Denitrate 1L - $8.99
Seachem Denitrate 2L - $14.99
Seachem Denitrate 4L - $21.99
Seachem Matrix
Seachem Matrix™ Filter Media is a high porosity biomedia that provides efficient biofiltration for the removal of nitrogenous waste. Matrix™ is a porous inorganic solid about 10 mm in diameter. Each liter of Matrix™ provides as much surface (less than 162 m) as 40 liters of plastic balls! Plastic bio-materials provide only external surface area, whereas Matrix™ provides internal macroporous surface area. These macropores are ideally sized for the support of nitrifying and denitrifying bacteria. This allows Matrix™, unlike other forms of biomedia, to remove nitrate along with ammonia and nitrite, simultaneously and in the same filter. Matrix™ is completely inert and will not breakdown. It need not be replaced. Use 1-2 Liters of Matrix™ for each 100 gallons. Since the majority of the bacteria are internal, Matrix™ may be rinsed when needed without damaging the filter. Matrix™ is compatible with all types of wet or wet-dry filters. Marine or freshwater use.
