Seachem Water Conditioners — The Foundation of Every Healthy Reef

Water quality is the absolute foundation of any successful reef aquarium. Before even thinking about corals or fish, the water must be perfectly conditioned. Seachem excels in this area with products that have become the industry standard.

Seachem Prime — The World's Most Used Conditioner

Seachem Prime is undoubtedly the world's best-selling and most recommended water conditioner for both freshwater and saltwater aquariums. Its ultra-concentrated formula not only neutralizes chlorine and chloramines in tap water, but also detoxifies ammonia, nitrites, and nitrates—a significant advantage when cycling a new aquarium or during periods of biological stress. Just one small dose of Prime effectively treats a large volume of water, making it one of the most economical products on the market despite its price. For any Canadian aquarist using municipal water, Prime is an absolute must-have.

Seachem Safe — Prime in Ultra-Concentrated Powder Version

Seachem Safe is the powdered version of Prime, even more concentrated. Ideal for aquarists who perform large, regular water changes or manage multiple systems, Safe offers the same spectrum of protection as Prime with even greater efficacy per gram of product. Its powder form also facilitates precise dosing and reduces shipping costs—a significant advantage for online orders in Canada.

Seachem Stability — Fast and Reliable Cycling

Seachem Stability contains a proprietary blend of aerobic and anaerobic nitrifying and denitrifying bacteria that quickly establish themselves in the filter and substrate to create a functional nitrogen cycle in minimal time. Unlike many competing products that contain unstable bacteria, Stability uses bacterial strains specifically selected for their effectiveness in marine aquariums. The result: faster cycling, a smoother transition when adding new specimens, and increased resilience of the biological system to chemical shocks.

Seachem Pristine — Biodegradation of Organic Waste

Seachem Pristine uses heterotrophic bacteria to actively break down organic waste, leftover food, and fecal matter before it can be converted into nitrates and phosphates. It's a natural and effective solution for maintaining crystal-clear water and reducing the overall organic load of the system—particularly useful in densely populated reefs or systems with high feeding activity.

Seachem Reef Additives — Complete Chemical Nutrition for Your Corals

Hard corals (SPS and LPS) constantly consume calcium, alkalinity, and magnesium to build their calcareous skeleton. Without a regular and balanced supply of these elements, growth stagnates and colors fade. The Seachem range of reef additives offers a scientific and modular approach to maintaining stable and optimal water chemistry.

Seachem Reef Fusion 1 & 2 — Complete System Calcium, Alkalinity and Magnesium

The Seachem Reef Fusion system is Seachem's two-part solution for simultaneously maintaining calcium, alkalinity, and magnesium at optimal levels for demanding reefs. Reef Fusion 1 provides readily available ionic calcium, while Reef Fusion 2 balances carbonate alkalinity and magnesium levels. Both products are formulated for use in tandem with precise dosing that adjusts to your reef's needs. This system is especially recommended for high-consumption SPS reefs where simpler calcium addition methods are insufficient.

Seachem Reef Builder — Pure Carbonate Alkalinity

Seachem Reef Builder increases carbonate alkalinity (KH/dKH) without raising the pH or adding sodium—a significant advantage because excess sodium can disrupt the ionic chemistry of seawater. Its powder formula dissolves completely and acts quickly, allowing for precise alkalinity adjustments without unwanted side effects. Ideal for use with an automatic dosing system to maintain a stable KH around 8-9 dKH.

Seachem Reef Calcium — Concentrated Ionic Calcium

Seachem Reef Calcium is a source of polymerized gluconate calcium that provides bioavailable calcium while also supplying a source of organic carbon usable by beneficial bacteria and certain corals. Its concentrated liquid formula allows for easy dosing and rapid absorption. Compatible with all automatic dosing systems.

Seachem Reef Complete — Calcium, Magnesium and Strontium

Seachem Reef Complete is a concentrated liquid supplement that provides calcium, magnesium, and strontium in a highly bioavailable form. Strontium is an essential trace element for coral calcification that is often overlooked in standard supplements. Reef Complete is a convenient solution for medium-sized reefs seeking comprehensive supplementation in a single product.

Seachem Reef Plus — Vitamins, Amino Acids and Trace Elements

Seachem Reef Plus is a complete nutrient complex that provides fat-soluble and water-soluble vitamins, essential amino acids, and a full spectrum of trace elements that corals, invertebrates, and reef fish cannot synthesize on their own. Regular use of Reef Plus visibly enhances coral coloration, strengthens fish immunity, and stimulates overall reef growth. It is a particularly popular product among aquarists who want to achieve vibrant colors without resorting to complex feeding methods.

Seachem Reef Trace — Essential Trace Elements

Seachem Reef Trace provides a full spectrum of trace elements—iodine, boron, fluorine, lithium, molybdenum, nickel, vanadium, and many more—that are continuously consumed by corals and invertebrates but present only in trace amounts in natural seawater. These elements are rapidly depleted in a closed system and must be replenished regularly to maintain water chemistry that closely mimics the ocean. Reef Trace is used in small weekly doses and combines perfectly with Reef Plus for comprehensive supplementation.

Seachem Chemical Filtration — Excellence in Water Treatment

Chemical filtration is the third pillar of water quality, after mechanical and biological filtration. Seachem has revolutionized this field with products that far surpass conventional solutions.

Seachem Purigen — The Absolute Reference in Organic Filtration

Seachem Purigen is a macroporous synthetic resin that outperforms conventional activated carbon in controlling nitrogen and organic waste. Purigen absorbs precursors of nitrates and nitrites, humic acids, proteins, and other dissolved organic compounds that yellow water and reduce clarity. Water treated with Purigen is incomparably clear and polished. Purigen's major advantage is its regenerability: when depleted (turning dark brown), it can be fully regenerated with a diluted bleach solution, then rinsed and reused—making it very economical in the long run. Purigen is available in ready-to-use sachets or in bulk for larger systems.

Seachem MatrixCarbon — High Performance Activated Carbon

Seachem MatrixCarbon is a high-quality activated carbon based on bituminous carbon, offering an exceptional adsorption surface for the removal of dissolved organic compounds, residual medications, and coloring agents. Its optimized microporous structure ensures maximum contact between the water and the medium. MatrixCarbon is particularly useful after medication treatment to purify the water before returning the reef to normal conditions.

Seachem PhosGuard — Rapid Control of Phosphates and Silicates

Seachem PhosGuard is an aluminum hydroxide-based adsorption medium that rapidly removes phosphates and silicates—the two main nutrients that promote the growth of unwanted algae in reef aquariums. PhosGuard is extremely effective even at very low phosphate concentrations, making it ideal for SPS reefs where maintaining phosphate below 0.03 ppm is crucial for vibrant corals. Its use in a fluidized bed reactor maximizes its effectiveness.

Seachem De*Nitrate — Natural Denitrification

Seachem De*Nitrate is a biological media with high internal porosity designed to create natural anaerobic zones where denitrifying bacteria reduce nitrates to harmless nitrogen gas. Its use at low flow rates in a reactor or low-agitation filtration compartment allows for the gradual reduction of nitrates without chemical intervention. Ideal for reefs that struggle to control nitrates despite regular water changes.

Seachem Matrix — Ultra-High Porosity Biological Media

Seachem Matrix is ​​a biological media made of natural pumice stone, offering a bacterial surface area of ​​160,000 m² per liter—one of the highest on the market. Its unique porosity simultaneously hosts aerobic bacteria on the surface (nitrification) and anaerobic bacteria in the depths (denitrification), creating a complete biological filtration system in a single medium. Matrix is ​​permanent, does not degrade, and never needs replacing—a one-time investment for the lifetime of your aquarium.

Seachem Water Tests — Precise Monitoring of Your Reef

Maintaining a healthy reef requires regular monitoring of water parameters. Seachem offers innovative testing tools that simplify this process.

Seachem MultiTest — Precise Multi-Parameter Tests

Seachem MultiTest kits allow you to test multiple parameters with a single compact kit—pH, ammonia, nitrite, nitrate, and phosphate, depending on the kit chosen. Seachem's analytical precision is evident in its tests, with stable reagents and clear color charts for reliable readings.

Seachem Ammonia Alert — Continuous Monitoring 24/7

The Seachem Ammonia Alert is a continuous monitor placed inside the aquarium that changes color in the presence of free ammonia—an early warning sign of a biological problem. Battery-free and requiring no manual testing, it monitors continuously for up to a year. Essential for quickly detecting an ammonia crisis during cycling or after the death of a specimen.

Seachem Nutrition and Supplements for Fish and Corals

Seachem Garlic Guard — Garlic Appetite Stimulant

Seachem Garlic Guard is a concentrated solution of natural garlic used to stimulate the appetite of picky or convalescent fish, and as a natural aid against external parasites such as ich and velvet. Simply soak the food in a few drops of Garlic Guard before feeding. Its effectiveness as an appetite stimulant is recognized by thousands of aquarists worldwide—especially useful for acclimating new wild-caught fish or helping stressed specimens resume eating.

Seachem Vitality, Nourish and Entice

Seachem Vitality is a complex of fat-soluble vitamins to improve the resistance and vitality of reef fish. Nourish provides essential amino acids often lacking in commercial fish foods. Entice is a versatile appetite stimulant that combines natural food attractants to encourage even the pickiest fish to feed regularly.
