  • Pristine Pristine

    Seachem Pristine

    Delivery in 2-5 Days  Excluding Weekends and Public Holidays

    Pristine uses bio-augmentation, a non-chemical and natural method, to improve water quality. It provides bacteria that break down excess food, waste and detritus in freshwater and marine systems. It will also reduce excess nutrients (e.g. ammonia, nitrates, and nitrites) that may fuel the growth of nuisance and disease-causing organisms. Pristine increases water clarity and promotes overall better health for the aquatic environment. The species of bacteria in Pristine are a unique blend, specifically developed for hardiness and their ability to adapt to a wide variety of environmental conditions.The bacteria species in Pristine thrive in fresh or salt water and can utilize a wide range of organic compounds, including fats that can cause unsightly films. Unlike traditional nitrifying bacteria, this bacterial blend can adapt to harsh or low oxygen environments and continue to multiply and improve water conditions. Biopolymers produced by established bacterial colonies trap particulates and increase water clarity.

  • DeNitrate DeNitrate

    Seachem DeNitrate

    Delivery in 2-5 Days  Excluding Weekends and Public Holidays

    DeNitrate 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 DeNitrate 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. DeNitrate removes nitrate by the same process. Efficiency is magnified several folds by forcing the water to filter through the porous DeNitrate. 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. DeNitrate 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.

  • Matrix Carbon Matrix Carbon

    Seachem Matrix Carbon

    Delivery in 2-5 Days  Excluding Weekends and Public Holidays

    MatrixCarbon is a truly unique activated carbon. It is formed as a spherical bead for optimum hydrodynamics, and will not pack. It permits maximum water flow and contact with its high density of macroporous binding sites. 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 detectable leachable phosphate content of all major carbon brands tested. MatrixCarbon outperforms other high grade carbons by at least two-fold when compared for total capacity to remove aquarium organic matter, rate of adsorption, and duration of use. While carbon is generally considered to be a chemical filter, that is not precisely true. It is in fact a mechanical filter as well, but it is only capable of mechanically filtering objects of molecular size. It functions through extremely small cracks and crevices, called macropores and micropores. Microporous carbons remove primarily metals and smaller ions (like trace minerals) and are best suited to air filtration, while macroporous carbons remove primarily larger organic molecules (like nitrogenous waste) and are best suited to water filtration. The ingredients from which a carbon is manufactured determine whether it will be macro- or microporous. Carbons made from coconut shell and other organic products form microporous carbons, while carbons made from bituminous coal form macroporous carbons. MatrixCarbon is a bituminous coal-based, macroporous carbon. It is the only spherical carbon on the market, allowing for maximum water flow. It is sized to allow full penetration by water, but not small enough to escape filter bags. All carbons contain phosphate. However, that phosphate DOES NOT come from washing the carbon with phosphoric acid. Most carbons are washed with sulfuric acid. The phosphate is contained in the ash from the carbon source. The main purpose of acid-washing is to remove ash. Because of MatrixCarbon's hydrodynamic properties, more ash is washed from our carbon than any other. Therefore, it has the lowest leachable phosphate on the market.

  • Seagel Seagel

    Seachem Seagel

    Delivery in 2-5 Days  Excluding Weekends and Public Holidays

    SeaGel is a blend of MatrixCarbon and PhosGuard and is is optimized specifically for aquaria where organic color body and acid removal is required without the introduction of phosphate. 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. SeaGel is optimized specifically for aquaria where organic color body and acid removal is required without the introduction of phosphate. 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.

    PhosGuard rapidly removes phosphate and silicate from marine and freshwater aquaria. Although PhosGuard is effective in both fresh and marine water, it will operate better in sea water and the need for it is better defined in sea water. It is not recommended for phosphate buffered freshwater (PhosGuard would remove the buffer until saturated). PhosGuard is highly porous and bead-shaped to promote easy water flow through and around it, thereby increasing both its efficiency and capacity.
