Top Seachem Products Recommendations

No. 1
Seachem Prime Fresh and Saltwater Conditioner - Chemical Remover and Detoxifier 500 ml
  • 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.
No. 2
Seachem Stability Fish Tank Stabilizer - For Freshwater and Marine Aquariums, 16.9 Fl Oz (Pack of 1)
  • 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.
No. 3
Seachem StressGuard Slime Coat Protection - Stress and Toxic Ammonia Reducer 500 ml
  • 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

1. Key Features to Look For

When you buy Seachem products, think about what your aquarium needs.

Water Conditioners and Additives

Medications and Treatments

3. Factors That Improve or Reduce Quality

Several things affect how well Seachem products work.

Factors That Improve Quality
  • Following Instructions: Using the correct dosage is key. Too much or too little can be less effective.

  • Tank Conditions: Healthy tank conditions help products work better. For example, good filtration supports bacterial growth.
Factors That Reduce Quality
  • Expiration Dates: Some products, especially those with live bacteria, have expiration dates. Using expired products can be less effective.
  • Overdosing: Using too much of a product can sometimes harm fish or disrupt the tank’s balance.
