    Seachem Alkanity Buffer - Ph and alkalinity stabilizer

    Seachem Alkanity Buffer - Ph and alkalinity stabilizer  Seachem Alkaline Buffer is a non‑phosphate buffering powder designed to raise and stabilise pH and increase alkalinity (KH) in freshwater aquariums. It’s especially useful if your water is too soft or acidic and you want a more stable, slightly alkaline environment.  What It Does Raises pH: Helps increase the water’s pH up to about 7.2–8.5 when used on its own. Boosts alkalinity (KH): Higher KH helps the water resist sudden pH swings — more stable water is healthier for fish and plants. Non‑phosphate: Unlike some other buffers, it doesn’t add phosphates that can contribute to algae growth.  How It’s Used Start with small doses — typically about 1 level teaspoon per ~80 L of aquarium water daily until you approach your desired pH and KH. It can be used on its own to raise pH, or combined with an acid buffer (like Seachem Acid Buffer) to target a specific pH range more precisely (e.g., for planted tanks).  Where It’s Most Useful Freshwater planted tanks with very soft or acidic tap water Water change top‑off water to help keep pH stable Tanks where stable pH is more important than chasing a precise number  Tips Always test pH and KH before and after adding it — too much buffer at once can shift pH rapidly, which can stress livestock. Slowly adjust over days for best results rather than doing big jumps. In summary, Seachem Alkaline Buffer helps your aquarium water resist pH swings by increasing alkalinity and gently raising pH — great for creating a stable freshwater environment.
