Seachem SeaGel

$10.10$151.30
  • Removes phosphate, silicate, organics, metals, acids, and more
  • 50/50 blend of MatrixCarbon and PhosGuard
  • More convenient than two separate bags of media

Description

SeaGel™ is a blend of MatrixCarbon™ and PhosGuard™. MatrixCarbon™ is an ultracapacity carbon for the removal of organic and color impurities. PhosGuard™ is a powerful remover of phosphate, silicate, toxic metals, and acids. Both components are bead shaped for optimum water flow characteristics and penetration. The components enhance each other and are ideal for reef and marine use. SeaGel™ may also be used in freshwater that is not phosphate buffered. Although MatrixCarbon™ has the lowest detectable leachable phosphate content of all major carbon brands tested, some phosphate is still released. Adding PhosGuard™ to the mix compensates for this. Both components are bead shaped for optimum water flow characteristics and penetration. The components enhance each other and are ideal for reef and marine use.

Directions

Use 250 mL for each 150–225 L (40–60 US gallons). Use in a filter bag such as Seachem’s The Bag™. Rinse in freshwater before use. Use caution, since product will fizz and heat on initial wetting. SeaGel™ will function 3–4 months.

Seachem Renew

$6.75$946.60
  • Phosphate-free carbon substitute
  • High pore # for maximum organic removal
  • Ideal to use in planted tank or marine tank - does not leach phosphate
  • No impact on trace minerals and important nutrients

Description

Renew™ is ideal for use in systems where phosphate released from all activated carbons poses a problem. Renew™ is also less aggressive than carbon, making it well suited for reefs and planted aquaria. It is also beneficial for use in soft water aquaria where the pH-raising property of many carbons is not an asset. Renew™ will remove organics and particulates in the sub-micron range; it will also help control ammonia, nitrates, and phosphates.

Directions

Renew™ should be used in exactly the same manner as activated carbon. Use 250 mL for each 120–160 L (30–40 US gallons). Use in a filter bag only. Although Renew™ is clean, it is advisable to rinse before use. It lasts about the same as carbon (4–6 weeks).

Seachem Purigen

$18.50$1,593.00
  • Highest organic removal capacity
  • Possesses enhanced capacity owing to its vast surface area; both spherical and macroreticular
  • Helps control ammonia/nitrite/nitrate
  • Color changes as it exhausts; easily regenerated

Description

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 other competing products by over 500%. Purigen® controls ammonia, nitrites and nitrates by removing nitrogenous organic waste that would otherwise release these harmful compounds. Purigen’s impact on trace elements is minimal. It significantly raises redox. It polishes water to unparalleled clarity. Purigen® darkens progressively as it exhausts, and is easily renewed by treating with bleach. Purigen® is designed for both marine and freshwater use. Selectivity: Purigen® is the highest capacity organic filtration resin on the market. No other products can compare to its ability to clear haziness and polish water to unparalleled clarity. Unlike other products on the market which are simple ion-exchange resins, Purigen® is specifically designed to be an organic scavenging resin. When ion-exchange resins are filled to capacity by metals and other contaminants, Purigen® has barely begun to reach its potential. Purigen® generally ignores simple elemental compounds, having an extreme affinity for nitrogenous organics. The primary source of nitrogenous compounds in an aquarium is waste. Fish, corals, even plants produce nitrogenous waste. Purigen® removes that waste faster and more completely than anything else on the market. Capacity: Purigen’s™ possesses enhanced capacity owing to its vast surface area. All other resins on the market are purely spherical extruded beads. These beads remain smooth even under a microscope. Purigen® is both spherical and macroreticular. It has microscopic pores that increase its usable surface area to many times that of a purely spherical resin. Regeneration: Purigen® can also be regenerated. As it adsorbs waste products, Purigen® will change color from a pale blonde to a dark brown, almost black. Once it 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. Watch out for products that claim to be regenerable with a brine solution. That is the regeneration procedure for ion-exchange purposes. A brine solution will not remove organics. While such resins have a limited capacity for organic adsorption, a brine regeneration process only replaces removed ionic compounds. It does not destroy large organic molecules that were removed, which is the primary function of organic adsorption resins.

Directions

Rinse before use. Use in a fine mesh (180 micron or less) filter bag such as Seachem’s The Bag™. Each 250 mL treats up to 1,000 L (250 US gallons) for up to six months. Exhaustion is indicated by a pronounced discoloration of the beads to dark brown or black. REGENERATION: Soak in a 1:1 bleach:water solution for 24 hours in a non-metallic container in a well ventilated area and away from children. Use regular 8.25% hypochlorite household bleach (non-scented, no dyes, do not use a splash-less bleach). Rinse well, then soak for 8 hours with a solution containing 4 tablespoons of Prime®, or equivalent dechlorinator per cup of water. Rinse well. For freshwater use, soak for 4 hours with a solution containing 2 tablespoons of buffer per cup of water (Discus Buffer®Neutral Regulator®). Original color and full activity should now be restored and Purigen® is ready for reuse. Caution: some slime coat products may permanently foul Purigen® and render regeneration difficult. Do not reuse if odor of bleach/chlorine is detectable. In case of doubt, soak beads in small quantity of water and test for residual chlorine with a chlorine test kit.

Seachem PhosGuard

$11.20$2,205.00
  • Removes silicate and phosphate
  • Spherical for optimal hydrodynamics
  • Irreversible binding

Description

PhosGuard™ rapidly removes phosphate and silicate from marine and freshwater aquaria. It is not recommended for phosphate buffered freshwater. PhosGuard™ is highly porous for high capacity and bead-shaped for optimum water flow.
Aluminum Oxide, Soluble Aluminum, and Coral Toxicity
In recent years, there has been speculation that aluminum oxide based phosphate removers like PhosGuard™ release aluminum into the water and subsequently damage corals. The evidence to support this claim was largely anecdotal. So, through a series of controlled experiments in both freshwater and saltwater, we intended to address both the question of aluminum solubility and aluminum toxicity. The results of these experiments show that under reef conditions (pH near 8) there is no detectable soluble aluminum released from alumina. Under conditions of low pH and high dosage levels, soluble aluminum can be released from alumina; at three times the label dosage rate, we detected 0.2 mg/L aluminum at a pH of 5.3. Additionally, aluminum oxide is not easily absorbed into the cell to cause negative reactions. Even at three times the dose of PhosGuard™, soft-bodied corals such as Sarcophyton remain unaffected. For the full report on this study, click here.

Directions

May generate heat on initial contact with water. Pre-wet by adding to a double volume of freshwater, followed by a rinse. For best results, PhosGuard™ should be rinsed before use and placed so as to maximize the flow of water through it but not so that it tumbles against itself in flow. It may be used in a canister filter, media chamber, box filter, or any high flow area of a trickle filter. Use of a filter bag is recommended. Use 85 mL (1/3 cup) for every 200 L (50 US gallons) saltwater or 400 L (100 US gallons) freshwater. Leave product in place for 4 days, then test phosphate or silicate concentrations with either MultiTest: Phosphate or MultiTest: Silicate. If the concentration of the component you are trying to decrease has not dropped to around 0.02 mg/L, then replace the PhosGuard™, otherwise leave in place until levels begin to climb again. As long as concentrations remain under control, the product is not exhausted. Over treating is not recommended. PhosGuard™ is not an exchange resin and does not release anything into the water. It does not leach phosphate or silicate back into the water and may be removed, dried, and returned to service until exhausted. Continuous use of small quantities is better than intermittent use of larger quantities.

Seachem Matrix

$10.30$1,232.00
  • High capacity biofiltration
  • Controls ammonia, nitrite, and nitrate
  • Highly porous - enormous surface area (>~700 m2/L)
  • Supports aerobic and anaerobic bacteria species

Description

Matrix™ 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 (>~700 m2) as 170 liters of plastic balls! Plastic bio-materials provide only external surface area, whereas Matrix™ provides both external and 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. 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.

Directions

Use 250 mL of Matrix™ for each 200 L (50 US gallons)** of water. Matrix™ may be placed in any kind of filter, and is particularly effective in a canister filter. Matrix™ is sufficiently large that no filter bag should be required for most applications. Matrix™ works well in drip tray systems, but you may find that the larger Pond Matrix™ is better suited for such applications. Use with Stability® to more rapidly establish the bio-filter. **This dosage may differ from your packaging. Based on updated studies, we've found Matrix™ treats even more water than previously asserted.

Surface Area of Matrix, Eheim Substrat Pro, and JBL MicroMec

Two competitors, Eheim (Substrat Pro) and JBL (MicroMec) have advertised their own biological filter media (in both cases, sintered glass) and are claiming larger specific surface areas than our claim for Matrix. For biological filter media, specific surface area (measured as surface area per gram of material, or surface area per some specified volume of material) is very important. These products provide surface sites for bacteria to attach and do their work. The greater the surface area per gram of medium, the greater the number of bacteria that can attach. Thus a high specific surface area is desirable. There is a second consideration, and that is the size of the pores in the medium. Generally, with very large pore diameters, we have smaller specific surface area, so that is not good. This generally rules out pores above 10 microns in diameter. But we can go too far in the other direction. If we have a very large number of very, very small pores, then our specific surface area number will be phenomenal, but the medium will not work very well as a biological medium. This is due to physical limitations, specifically too small a volume to support bacterial growth, and the decreasing efficiency of fluid transport (necessary to carry nutrients to the bacteria and waste away from the bacteria) with very small pore sizes. (Small pores still play important roles in physical and chemical processes, such as adsorption.) BET surface area measurements indicate that Matrix™ contains nearly 10 times the specific surface area of Substrat Pro, and more than 20 times the specific surface area of MicroMec. Practically all the specific surface area of both Substrat Pro and MicroMec are in the range of pore diameters to be biologically useful, while some of the surface area of Matrix is in pores that are reserved for physical and chemical processes, not biological processes. Estimates from two different pore geometries indicate that Matrix contains between 4 to 4.5 times the biologically active surface area of Substrat Pro, and between 8 to 9 times the biologically active surface area of MicroMec.

Seachem HyperSorb

$16.10$24.50
  • High capacity organic waste removal
  • Synthetic adsorbent
  • Economical carbon substitute
  • No impact on pH; minimal impact on trace elements

Description

HyperSorb™ is a synthetic adsorbent that outperforms all other blended synthetic media and carbons. It has exceptional organic removal capacity: it removes organic waste, toxic vapors and other pollutants. In freshwater it will help stabilize the ionic balance and will help control ammonia, nitrite, and nitrate. It is easily regenerated with household bleach. For use in both freshwater and marine.

Directions

Use in a filter bag such as The Bag. Each 250 mL treats up to 300 L (75 US gallons). Rinse before use. Exhaustion is indicated by a pronounced discoloration of the beads from yellow to deep brown. REGENERATION: Soak in a 1:1 bleach:water solution for 24 hours in a non-metallic container in a well ventilated area and away from children. Use regular 8.25% hypochlorite household bleach (non-scented, no dyes, do not use a splash-less bleach). Rinse well, then soak for 8 hours with a solution containing 4 tablespoons of Prime®, or equivalent dechlorinator per cup of water. Rinse well. For freshwater use, soak for 4 hours with a solution containing 2 tablespoons of buffer per cup of water (Discus Buffer®Neutral Regulator®). Original color and full activity should now be restored and HyperSorb™ is ready for reuse. Caution: some slime coat products may permanently foul HyperSorb™ and render regeneration difficult. Do not reuse if odor of bleach/chlorine is detectable. In case of doubt, soak beads in small quantity of water and test for residual chlorine with a chlorine test kit.

Seachem De*nitrate

$7.20$94.80
  • Removes nitrates, nitrites, ammonia, and organics
  • High porosity biological media
  • Pore size well suited for anaerobic bacteria
  • No danger of hydrogen sulfide production as with sulfur based media

Description

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. “Live” rocks or reef rocks remove nitrate by anaerobic denitrification. de*nitrate™ removes nitrate by the same process. Efficiency is magnified several folds by forcing the water to filter through the porous de*nitrate™. As with reef rock, anaerobic conditions are achieved by the porosity and the depletion of oxygen by the aerobic process at the surface. Excessive flow rates should, therefore, be avoided, as they may impede development of an adequate anaerobic environment to support denitrifying bacteria. de*nitrate™ is also an excellent media for aerobic nitrification and it makes an ideal biological filter in drip trays, canister filters, sumps, or even box filters. At high flow rates (greater than 100 US gallons per hour), it will function solely as an aerobic filter. At slow flow rates (less than 50 US gallons per hour), it will function as both an aerobic filter and an anaerobic denitrifying filter.

Directions

For best results, de*nitrate™ should be placed to assure the flow of water through it, such as in a canister filter, chemical filtration module, or box filter. Flow rate should not exceed 200 L (50 US gallons) per hour. If higher flow rates are unavoidable, use Matrix™ or Pond Matrix™. It is best to rinse off dust before use. Once de*nitrate™ has been in use for several days, nitrate concentrations should start to fall and level off gradually at a concentration of about 4–5 mg/L as nitrate. As long as nitrate concentrations remain under control, the product is not exhausted. Each 500 mL of de*nitrate™ treats about 100–200 L (25–50 US gallons), depending on initial nitrate concentration and the current biological load. Enough should be used to remove nitrate at a rate at least as fast as the rate of formation. If very high nitrates are initially present, they should be brought down to less than 20 mg/L with water changes.
