    Seachem Purigen is a tool that every hobbyist, both beginner and advanced, should have in their aquatic tool kit. It is a scientifically formulated premium synthetic adsorbent that is not a mixture of ion exchangers or adsorbents, but a unique macro-porous synthetic polymer that removes soluble and insoluble impurities from both freshwater and saltwater at a rate and capacity that exceeds all other competitive products by over 500%. The formula helps to control ammonia, nitrites and nitrates by removing nitrogenous organic waste that would build up and release harmful chemicals into your aquarium water column, negatively impacting all aquatic life within the aquarium. Though Purigen's impact on beneficial trace elements is minimal, it significantly raises redox and polishes water with unparalleled clarity. Seachem Purigen's ability to clear haziness and polish water is unparalleled in the market today. Unlike other available competitive products which are just basic ion-exchange resins, this solution is specifically designed to be an organic scavenging resin and generally ignores simple elemental compounds, having an extreme affinity for nitrogenous organics. Nitrogenous compounds come from aquarium waste produced by fish, coral, as well as plants. The Purigen beads are uniquely spherical and macro-reticular in shape and the increased surface area provides an enhanced capacity with microscopic pores that increase its usable surface area to many times that of other products on the market, which are made of purely spherical resin. The versatile product can be used in a wide variety of filtration applications such as in a canister filter, media chamber, box filter, or any high flow area of a trickle filter. To add to the already incredibly functionality of this product, Purigen can actually be regenerated to retain efficiency and effectiveness in the long term. As it adsorbs waste products, the beads will change colour from a pale blonde to a dark brown, nearly black coloration. 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. Brine solutions will not remove necessary harmful organics. While such resins have a limited capacity for organic adsorption, a brine regeneration process only replaces removed ionic compounds and it does not destroy large organic molecules that were removed, which is the primary function of organic adsorption resins in the first place.

    The Seapora Poly Pad is a dense mechanical filter pad fabricated to remove fine/coarse particulate matter from your aquarium system. This process prevents obstructions in the biological media, thereby diminishing the risk of fish stress and disease. It also helps keep your aquarium water crystal clear! 18" x 10" The Seapora Carbon Pad is a dense chemical filter pad designed to absorb dissolved organic matter, remnants of medications, and tannins from driftwood. It also facilitates the removal of particulates, odours, and discolouration from your aquarium system. 18" x 10" The Seapora Ammonia Pad is a dense chemical filter pad that removes Ammonia from your aquarium water; effectively reducing the possibility of Ammonia poisoning. Seapora Ammonia Pads lower the risk of fish stress and disease while promoting crystal clear water. This media should be implemented as a preventative measure or treatment; and not as a remedy for persistent Ammonia concentrations. 18" x 10" The Seapora Nitrate + Nitrite Pad is a dense chemical filter pad that neutralizes nitrate and toxic nitrite in freshwater aquariums. It reduces the possibility of nitrite poisoning and helps reduce fish stress caused by the presence of nitrite. Nitrates can cause kidney, liver and eye problems in fish, as well as appetite suppression. 18" x 10" The Seapora Phos Pad is a dense chemical filter pad that absorbs phosphate from your aquarium. In high concentrations, phosphate is a major food source for troublesome algae. Phosphate gradually accumulates due to overfeeding, lack of regular maintenance, and decaying organic matter. 18" x 10"

  • Seachem De*nitrate Seachem De*nitrate

    Seachem Laboratories Seachem De*nitrate

    Out of stock

    Seachem De*Nitrate is a top-of-the-line filter media designed specifically to provide additional support to the biological filtration process. The media itself is an economical, natural, porous material sporting a pore distribution, shape and large surface area that encourages beneficial anaerobic nitrification within the first few millimetres of depth and anaerobic denitrification at the core. Additionally, the media helps to remove harmful nitrates, nitrites, ammonia and organics that can cause harm or even kill your aquatic inhabitants. Live rocks or reef rocks remove nitrate by anaerobic denitrification and Seachem De*Nitrate removes nitrate using the same process, except the efficiency of this process is magnified several folds by directing the water to filter through the porous filter media. Due to this process, excessive flow rates should be avoided, as they may impede the development of an adequate anaerobic environment to support denitrifying bacteria and as is the case with reef rock, anaerobic conditions are achieved by the porosity and the depletion of oxygen by the aerobic process at the surface. De*Nitrate is an exceptional media for aerobic nitrification as well, making it an ideal biological filter in drip trays, canister filters, sumps or even box filters. As mentioned earlier, it is important to note that at high flow rates (greater than 100 GPH), it will function solely as an aerobic filter and at slow flow rates (less than 50 GPH), it will function as both an aerobic filter and an anaerobic denitrifying filter. Suitable for use in both freshwater and saltwater environments.

    Seachem Matrix Bio-Media is a professional grade high porosity bio-media designed to provide efficient biofiltration specifically for the targeted removal of nitrogenous waste in both freshwater and marine aquariums. This high capacity biofiltration helps to control harmful compounds in your aquarium such as ammonia, nitrate and nitrite, effectively keeping these elements at safe levels as to not harm the aquatic inhabitants of your tank. The media is an inorganic solid approximately 10 mm in diameter and boasts an exceptionally large surface area, with each litre of Seachem Matrix Bio-Media providing as much surface area (<162 m) as 40 litres of plastic bio-balls! The difference in efficacy and space-saving ability will make your head spin! As well, many plastic bio-materials only provide an external surface area for bacteria cultivation, whereas this media offers a spacious internal macroporous surface area with macropores that are the optimal size to support beneficial nitrifying and denitrifying bacteria. Unlike other common forms of bio-media, this allows Seachem Matrix Bio-Media to easily remove nitrate along with ammonia and nitrite, simultaneously and in the same filter for a more efficient and effective process. The media is completely inert and will not break down, nor does it need to be replaced. It is also compatible with nearly every type of wet and wet-dry filter. Use 250 mL of Seachem Matrix for each 200 L (50 US gallons) of aquarium water. The media may be placed in any kind of filter and is noticeably effective when used in a canister filter. The media is sufficiently large enough that no filter bag should be required for most applications. It works quite well in a variety of drip tray systems but may find that the larger Seachem Pond Matrix is better suited for such applications
