Seachem Prime Fresh and Saltwater Conditioner - Chemical Remover and Detoxifier 500 ml

Aquarium Water Treatments

Buy on Amazon Find on eBay

POWERFUL TREATMENT: Seachem Prime is a complete and concentrated conditioner for both freshwater and saltwater fish tanks, working hard to remove chlorine and chloramine.

REMOVER: Seachem Prime immediately and permanently removes chlorine and chloramine, successfully allowing the bio filter to remove ammonia, nitrite, and nitrate while they are detoxified for 48 hours.

DETOXIFIER: Seachem Prime effectively detoxifies ammonia, nitrite, and heavy metals found in the tap water at typical concentration levels, providing a ideal environment for your betta, tetra, or other fish.

USE: Use 1 capful (5 mL) of Seachem Prime for each 200 L (50 US gallons) of new or replacement water. For best results, add Seachem Prime to new water first. For exceptionally high chloramine concentrations, a double dose may be used safely. For smaller volumes, use 2 drops per gallon.

SAFETY: In case of an emergency, the 5x dose of Seachem Prime may be used for both ammonia and nitrite. Use a ½ dose if the water temperature is > 30°C (86°F) and chlorine or ammonia levels are low.

Seachem Stability Fish Tank Stabilizer - For Freshwater and Marine Aquariums, 16.9 Fl Oz (Pack of 1)

Aquarium Water Treatments

Buy on Amazon Find on eBay

TANK STABILIZATION: 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".

TREATMENT: 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.

BACTERIA GROWTH: The necessary conditions for the growth of Stability's bacteria strains encompass a very broad range. When other bacteria begin to die off (usually from high organic loads caused by the unknown death of an organism), Stability simply becomes more effective.

USE: Shake Seachem Stability well before use and turn off UV/ozone filter. Use 1 capful (5 mL) for each 40 L (10 US gallons) on the first day with a new aquarium. Then use 1 capful for each 80 L (20 US gallons) daily for 7 days. Fish and other aquatic species may be introduced at any time as long as dosage is maintained for 7 days.

SAFE: The bacteria employed by Stability are non-sulfur fixing and will not produce toxic hydrogen sulfide. Stability is completely harmless to all aquatic organisms as well as aquatic plants, thus there is no danger of overuse.

Seachem Indoor Purigen Organic Filtration Resin - Fresh and Saltwater 100 ml

Aquarium Test Kits

Buy on Amazon Find on eBay

FILTRATION: Purigen ranges in color from almost white (cream) to light yellow. Seachem Purigen is not a mixture of ion exchangers or adsorbents, but a unique macro-porous synthetic polymer that removes soluble and insoluble impurities from water.

SELECTIVITY: Seachem Purigen is an organic filtration resin that works hard to remove nitrogenous compounds and waste produced by fish, corals, and even plants, making your water crystal clear.

CAPACITY: Being both spherical and macroreticular, Seachem Purigen has microscopic pores that increase its usable surface area to many times that of a purely spherical resin.

REGENERATION: Once Seachem's Purigen 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.

SAFETY: 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 StressGuard Slime Coat Protection - Stress and Toxic Ammonia Reducer 500 ml

Aquarium Water Treatments

Buy on Amazon Find on eBay

PROTECT: Seachem StressGuard is a premium slime coat protection product, working to reduce stress and ammonia toxicity whenever handling or transporting ﬁsh.

HEAL: Seachem StressGuard binds to exposed protein in wounds to promote healing of injured ﬁsh while reducing the likelihood of primary and secondary infections.

TREATMENT: The protein active colloidal agent in StressGuard actively seeks out any wounds, abrasions, or places where exposed proteins are and attaches to this area, helping to directly deliver the disinfectant in the product and start the healing process.

AQUARIUM CARE: Use 1/2–1 capful (2.5–5 mL) of StressGuard to every 40 L (10 US gallons) every 24 hours until signs of stress have abated or healing is complete. A dose of StressGuard may be safely doubled.

SAFETY: StressGuard has a pH of 7.0. It will not affect the pH of an aquarium, even at large doses, allowing for safe use in a reef or planted aquarium containing invertebrates

Seachem Pristine Aquarium Treatment, 500ml (001438)

Aquarium Water Treatments

Buy on Amazon Find on eBay

Included Components: Seachem Pristine Aquarium Treatment, 500Ml

Seachem Flourish Excel 500 ml

Aquarium Water Treatments

Buy on Amazon Find on eBay

CARBON PRODUCTION: All plants require a source of carbon, and Flourish Excel is a great and convenient source of bioavailable organic carbon.

IRON PRODUCTION: Flourish Excel also possesses iron reducing properties, thus promoting the ferrous state of iron (Fe+2), which is more easily utilized by plants than ferric iron (Fe+3).

PHOTOSYNTHESIS: Plants must produce longer chain carbon compounds (photosynthetic intermediates). By dosing with Flourish Excel you bypass the involvement of chain carbon compounds, and introduce the already finished, structurally similar compounds.

TREATMENT: On initial use or after a major (> 40%) water change, use 1 capful of Flourish Excel (5 mL) for every 40 L (10 US gallons). Thereafter, use 1 capful for every 200 L (50 US gallons) daily or every other day. For smaller dosing please note that each cap thread is approximately 1 mL.

SAFETY: Flourish Excel is completely safe for fish, however if you have Anacharis in an aquarium in which you are dosing Flourish Excel, then it is recommended to use it every other day rather than daily.

Seachem Flourish Tabs Growth Supplement - Aquatic Plant Stimulant 40 ct

VITAMINS: Seachem Flourish Tabs are rich in iron, manganese, magnesium, calcium, potassium, inositol, choline B12, biotin, and other factors that have been determined to be beneficial to aquatic plant roots.

NUTRIENTS: When inserted into the gravel, Seachem Flourish Tabs provide direct, time-released fertilization to the plants' root zone. Nutrients are slowly made available through enzymatic action of the plants' roots on the tabs.

TANK USE: Insert one Flourish Tab in the gravel for every 10–15 cm (4–6 in.) radius. A standard 10 gallon aquarium requires 6 tabs. Distribute the tablets evenly throughout the gravel bed, pushing each tablet midway into the gravel bed.

COMPLETE MAINTENANCE: For optimal plant growth, add new Flourish Tabs to the aquarium once every three to four months. Seachem Flourish Tabs will not alter pH, however, in very soft or unbuffered water, they have slightly acidic properties similar to peat moss.
