Seachem Acid Buffer 600 g – Non-Phosphate pH Lowering Buffer for Planted Aquariums

Overview

Seachem Acid Buffer 600 g is a non-phosphate acid buffer designed to help lower and stabilize pH in planted aquariums and in very hard water. When used with Alkaline Buffer, Acid Buffer adjusts pH within a practical range from 5.0 to 8.0, offering a plant-friendly environment without introducing phosphates.

How it works

The product lowers pH by releasing acid and, as pH decreases, carbonate alkalinity (KH) is converted into available CO2 that plants can use. This helps balance the CO2 available for photosynthesis and growth in densely planted setups.

• Non-phosphate formula reduces the risk of phosphate-related algae or cloudiness in sensitive setups.
• Designed for planted aquariums and water with high hardness, where some buffers may not be ideal.

Pairing and maintenance

For best results, use Acid Buffer together with Alkaline Buffer. The two products form a buffering system that can keep pH in a usable range while avoiding excess phosphates. If you prefer a phosphate-based buffering option, consider Acid Regulator, which offers a different balance between pH stability and phosphate content.

• Acid Buffer is a straight acid source; Acid Regulator is phosphate-based and can offer steadier pH in some conditions.
• Begin with small doses and monitor pH, KH, and plant response to tailor dosing to your aquascape.

Note: The formulation is designed to support planted tanks and hard water scenarios; results depend on water chemistry, stocking, and plant demand. Always follow label directions and adjust dosing gradually to avoid large, rapid shifts in pH.
