Seachem Marine Buffer is a specialized, multi-component blend designed to safely raise and maintain the pH of saltwater aquariums at a stable 8.3. Unlike simple sodium bicarbonate or carbonate products, Marine Buffer is engineered to never exceed pH 8.3, even in the event of an accidental overdose. This makes it the safest and most effective solution for managing the complex buffering needs of marine fish and reef environments.
Marine Buffer uses a sophisticated blend of salts to combat the natural tendency of aquarium water to become acidic.
Automatic pH Cap: The unique formulation ensures that the pH will not rise above 8.3, protecting your livestock from dangerous alkaline spikes.
Borate-Enhanced Stability: The first buffer to incorporate borate salts, which significantly increase the stability of the buffering system against pH shifts.
Magnesium Support: Contains magnesium to help prevent the precipitation of calcium and other minerals, maintaining a balanced ionic profile.
Comprehensive Mineral Blend: Features a balanced mix of sodium, magnesium, calcium, strontium, and potassium salts of carbonate, bicarbonate, chloride, sulfate, and borate.
Improved Effectiveness: The product becomes increasingly effective with continued use, creating a more resilient biological environment.
How do I dose Seachem Marine Buffer? Add 5 g (1 level teaspoon) for every 80 L (20 US gallons). Dissolve the powder in at least one cup of freshwater before adding it to the tank. Dose daily until the pH stabilizes at 8.3, then use biweekly or monthly to maintain.
Is Marine Buffer safe for reef tanks? Yes, it is completely reef-safe. However, for reef systems with very high organic loads and heavy acid production, Seachem Reef Buffer (which has a higher pK of 8.6) may be more effective at holding the pH at 8.3.
What if a white precipitate forms after I add it? A slight, flaky white precipitate is temporary magnesium carbonate and should redissolve within 30 minutes. If a large precipitate persists for more than 15 minutes, it indicates an ionic imbalance, and a water change is recommended before further dosing.
Seachem Marine Trace: Replenish the vital micro-minerals and trace elements utilized by marine fish alongside your buffer maintenance.
Seachem MultiTest Marine pH & Alkalinity: Use this high-accuracy kit to precisely monitor your parameters and determine your dosing schedule.
Seachem Reef Buffer: The ideal alternative for high-load reef systems that require a more aggressive buffering agent to maintain 8.3.
