Seachem Laboratories Alkaline Buffer Aquarium Water Treatment, 1.3 lb

Keeping your freshwater aquarium happy comes down to water you can rely on, and Seachem Laboratories Alkaline Buffer in the 1.3 lb size is a dependable helper. This is a non-phosphate buffer made to raise pH and alkalinity (KH) for your tank. The 1.3 lb size gives you a solid, longer-lasting supply for established aquariums or anyone who treats their water on a regular schedule and does not want to reorder too often.

• It raises pH and alkalinity (KH), helping your fish live in water that holds a more stable, supportive range.
• As a non-phosphate buffer, the brand notes it is designed for the planted aquarium or for very hard water where phosphate buffers may pose an algae or cloudiness problem.
• It is made to buffer with Acid Buffer, so you have a two-part way to fine-tune your readings rather than guessing.
• Seachem says it buffers between 7.2 and 8.5, a useful window for many freshwater community tanks.
• The brand calls it gentle and safe, letting you treat your water with confidence instead of worry.
• It is meant to enhance the freshwater environment, supporting the aquarium you have carefully set up.
• The 1.3 lb size offers a generous supply, cutting down how often you restock for active tanks.
• Leaving out phosphate makes it well suited to planted tanks where algae and cloudiness are a concern.
• Combined with Acid Buffer, it gives you tighter control over where pH and alkalinity land.
• It slips easily into a consistent water-care routine between maintenance days.

A freshwater tank thrives when its water stays in a steady, livable range, and the right buffer makes that goal much easier to reach. Choose the 1.3 lb Seachem Alkaline Buffer when you want a non-phosphate, planted-tank-friendly way to raise pH and alkalinity with enough on hand for regular care. Your fish get a more comfortable home, and you get peace of mind every time you check the water.
