Lowers KH to lower pH in stubbornly high pH water.

Uses: Acid Buffer is used in conjunction with Neutral Regulator when the pH is very high or is difficult to lower to 7.0 with Neutral Regulator. It reduces the carbonate hardness (KH) of the water, making the pH much easier for other products to buffer. If your pH is very high and resistant to buffering, Acid Buffer is your answer! Consider using with our other Seachem products!

From the manufacturer: 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 5.0 and 8.0 when used with Alkaline Buffer. As Acid Buffer lowers pH, it converts carbonate alkalinity (KH) into available CO2. It may also be used to safely lower pH in marine water.

Directions from the manufacturer: To lower pH, use 1/4 teaspoon (2 grams) for every 20 gallons (80 liters) 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.
