Seachem LIQUID Acid Buffer 250ml

£10.60 £10.59

Product Description

Liquid Acid Buffer™is a non-phosphate buffer to lower pH and buffer with Liquid Alkaline Buffer™. Both buffers are designed for the planted aquarium or for very hard water where phosphate buffers may pose an algae or cloudiness problem. Liquid Acid Buffer™ lowers pH and buffers between 5.0 and 8.0 when used with Liquid Alkaline Buffer™. As Liquid Acid Buffer™ lowers pH it converts carbonate alkalinity into available CO2.

Sizes: 100 mL, 250 mL, 500 mL, 2 L, 4 L, 20 L



Why It’s Different?

What distinguishes Liquid Acid Buffer™ from other buffers is that it does not contain phosphates. This makes it ideal for the planted aquarium, where excess phosphate could contribute to undesirable algae growth.


Use 1 capful (5 mL) for every 10 L (2.5 gallons*) daily until desired pH is reached (this dose lowers alkalinity by about 0.08 meq/L (0.3 dKH)). If water is soft or not well buffered, use with Liquid Alkaline Buffer™ (see below). Larger doses may be required in very hard (KH) alkaline waters. TIPS: Liquid Acid Buffer™ will not raise pH. It may be added directly to the aquarium at any time.

Use these ratios to target pH
