Seachem Acid Buffer

Designed specifically for planted aquariums or systems with very hard water, where phosphate-based buffers can cause algae or turbidity problems. Acid Buffer lowers pH and stabilizes it between 5.0 and 8.0. By lowering the pH, its formula converts carbonate alkalinity (KH) into available CO₂, benefiting your plants. It can also be safely used to lower pH in saltwater.
