Description

Seachem Acid BufferSeachem Acid Buffer Acid Buffer is a nonphosphate buffer to lower pH and buffer with 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. Acid Buffer lowers pH and buffers between 6. 0 and 8. 0 when used with Alkaline Buffer. As Acid Buffer lowers pH it converts carbonate alkalinity (KH) into available CO2. Adjusts pH to 5. 08. 0 Designed for use in

Seachem Acid Buffer

Acid Buffer™ is a non–phosphate buffer to lower pH and buffer with 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. Acid Buffer™ lowers pH and buffers between 6.0 and 8.0 when used with Alkaline Buffer™. As Acid Buffer™ lowers pH it converts carbonate alkalinity (KH) into available CO2.

  • Adjusts pH to 5.0—8.0
  • Designed for use in planted aquariums
  • Converts carbonate alkalinity (KH) into available CO2
  • Contains no phosphate

Directions

To lower pH, use 1/4 teaspoon (2g) for every 80 L (20 US gallons) daily until desired pH is reached (this dose lowers alkalinity by about 0.2 meq/L (0.6 dKH)). Larger doses may be required in very hard (KH) or alkaline waters. For precise dosing, use the Seachem Digital Spoon Scale.

In order to adjust pH gradually, or if water is soft or not well buffered, use Acid Buffer™ with Alkaline Buffer™. When using Alkaline Buffer™ & Acid Buffer™ together to target a specific pH, utilize the suggested ratio chart.

HINT: First determine the amount of Alkaline Buffer™ needed for the volume of water. This should be determined based upon your desired alkalinity (KH). Then, divide by the number in the middle column to obtain the correct amount of Acid Buffer™ required.

This chart is based on use in RO or RO/DI water and ratios may need to be adjusted for use in tap water.

Acid Buffer Alkaline Buffer pH
1 1.3 6.5
1 2.0 7.0
1 2.5 7.5
1 4.0 8.0

 

CAUTION: Causes serious eye irritation. Keep out of reach of children. Avoid contact with skin.
