Seachem Chlorguard 250ml Seachem Chlorguard 250ml


Seachem ChlorGuard safely, rapidly and effciently removes toxic chlorine. Chlorine is commonly used in many municipal water sources to disinfect tap water. Chlorine is toxic to all aquatic life and should be removed before use of such water. ChlorGuard should be used whenever doing a water change or adding water. Be aware that many municipalities treat water with chloramines rather than chlorine. Seachem ChlorGuard will not remove chloramines. Check with your municipality water provider if you are uncertain which is used in your area. If chloramines are used, then use Seachem Prime instead. Seachem ChlorGuard is an econmical alternative to Seachem Prime when the additional benefits of Seachem Prime are not needed. Seachem Chlorguard is safe for freshwater and marine.

Seachem Clarity is the ultimate clarifier for both fresh and saltwater. It employs an advanced polymeric flocculating agent that is both reef and plant safe. Seachem Clarity is the only clarifier on the market that does it all! Clarity will clear all types of clouding: bacterial and other biological type blooms, chemical clouding, and particulate clouding (i.e. stirred up gravel bed). When Clarity clears up bacterial clouding it helps to accelerate and enhance the colonization of the biological filter by efficiently relocating these natural biofilms to the biosupport media in the filter. Freshwater and Marine. Plant and reef safe.

Seachem Livebearer Salt 300 gramSeachem Livebearer Salt 300 gram
Seachem Live Bearer Salt is a blend of specific salts designed to accurately duplicate the natural environment of live bearing and brackish water fish.

Unlike other aquarium salts currently available to the hobbyist, Seachem Live Bearer Salt is more than just a simple sodium chloride product. These other salts can burn leaves and roots in a planted aquarium.

However, Seachem Live Bearer Salt does not cause this type of damage, and actually provides many nutrients crucial to healthy plant growth. Dosing of Seachem Live Bearer Salt allows for specific duplication of different brackish water environments found worldwide (such as the waters of Sumatra or the waters of Borneo). Live Bearer Salt can also be dosed for general brackish water community aquariums and general freshwater community aquarium. Seachem Live Bearer Salt is a safe and effective alternative to the sodium chloride based aquarium salts so prevalent on the market today.


DIRECTIONS: Use when setting up an aquarium and when making water changes. To add salt to an established tank, do so gradually. It is best to predissolve the salt in freshwater before use. Avoid using salt when simply replacing evaporated water.

For live bearers (such as guppies, swordtails, platies, some mollies), use 20 g (~1 tablespoon) for each 10 gallons (40 L).
For estuary fish from the Yucatan or Sri Lanka (Archers, Chromides, some mollies), use 15 g (~2 teaspoons) for each 3 gallons (12 L).
For estuary fish from Thailand, Cambodia, Borneo, or Sumatra (Datinoides), use 40 g (~2 tablespoons) per 3 gallons (12 L).
For scats, use up to 80 g (~4 tablespoons) per 3 gallons (12 L). This dose is not for planted aquaria.
For mixed populations, use an average dose, representative of species present. For specific information on your fish, check with your dealer or reference an atlas.
For general aquarium salt use (either for mineral replacement or disease control), use 20 g (~1 tablespoon) for each 10 gallons (40 L).

Seachem Malawi / Victoria Buffer is a blend of carbonate salts designed to enhance the natural environment of cichlids by increasing hardness, buffer capacity, and pH. Seachem Malawi / Victoria Buffer is formulated to maintain a pH of 7.8-8.4. For optimum replication of the Malawi / Victoria environment, use with Seachem Cichlid Lake Salt.

DIRECTIONS: Use 5 g (1 level teaspoon) of Seachem Liquid Malawi Buffer for each 40–80 L (10 to 20 gallons*) of water each day until desired pH is attained and maintained. Thereafter, use as required to maintain pH, usually no more than once every two to three weeks. TIPS: It is best to dissolve the Seachem Liquid Malawi Buffer in freshwater before use. Use when setting up an aquarium or making water changes (preferably after the addition of Seachem’s Cichlid Lake Salt™) and between water changes as needed to maintain pH. Seachem’s Malawi / Victoria Buffer™ is formulated to maintain a pH between 7.8 and 8.4, depending on the amount used. To attain a lower pH than 7.8, you may use Seachem’s Acid Buffer™ in combination with Malawi / Victoria Buffer™. To attain a higher pH than 8.4, use Tanganyika Buffer™.

Seachem Matrix Carbon 500mlSeachem Matrix Carbon 500ml

Seachem Matrix Carbon 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. Seachem Matrix Carbon 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, Seachem Matrix Carbon has the lowest detectable leachable phosphate content of all major carbon brands tested. Seachem Matrix Carbon out performs 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. This product is sold by volume. Cited weight is minimal weight.

Sizes: 100 mL (bagged), 250 mL, 500 mL, 1 L, 2 L, 4 L, 20 L, 100 L

DIRECTIONS: 250 mL will easily treat 400 L (100 gallons*) for several months. Seachem Matrix Carbon is very clean and nearly dust free. For best results, Seachem Matrix Carbon should be placed so as to maximize the flow of water through it. It may be used in a canister filter, chemical filtration module, box filter, or any high flow area of a trickle filter.

Seachem Amguard 250mlSeachem Amguard 250ml

Seachem AmGuard safely, rapidly and efficiently removes toxic free ammonia. It is safe to use during tank cycling and is ideal for treating unexpected emergency situations. Seachem AmGuard reacts with free ammonia within minutes and does not alter pH. Ammonia can exist in two forms: free and ionized. It is only the free form that is toxic. Traditional ammonia test kits convert all ammonia to free ammonia by raising pH to 12 14; at this pH Seachem AmGuard cannot function and thus a false positive reading will result. Use Seachem Ammonia Alert or Seachem MultiTest: Free & Total Ammonia to directly monitor levels of free ammonia. Seachem AmGuard also removes chlorine and chloramines.

Seachem Stability 100mlSeachem Stability 100ml

Seachem Stability will rapidly and safely establish the aquarium biofilter in freshwater and marine systems, thereby preventing the #1 cause of fish death: "new tank syndrome". Stability is formulated specifically for the aquarium and contains a synergistic blend of aerobic, anaerobic, and facultative bacteria which facilitate the breakdown of waste organics, ammonia, nitrite and nitrate. Unlike competing products, the bacteria employed by Stability are non-sulfur fixing and will not produce toxic hydrogen sulfide. Seachem Stability is completely harmless to all aquatic organisms as well as aquatic plants, thus there is no danger of over use. Seachem Stability is the culmination of nearly a decade of research and development and represents the current state of the art in natural biological management.
