Seachem Alkaline Buffer is a non-phosphate buffer designed to raise pH and alkalinity (KH) in freshwater aquariums. It is ideal for planted tanks and hard water setups where phosphate-based buffers may encourage algae growth or cloudy water. When used correctly, it can raise pH to between 7.2 and 8.5 and is completely safe for both fish and plants.
Key Points
- Non-phosphate buffer for safely raising pH and KH
