Seachem Acid Buffer is designed to lower the pH level in your marine aquarium. It is a non-phosphate buffer designed to buffer between 5.0 and 8.0.
As Seachem Acid Buffer lowers pH it converts carbonate alkalinity into CO2 and may also be used to safely lower the pH levels in marine water. To reduce the pH level add 2g of Acid Buffer per 80 litres of aquarium water until you reach the desired level of pH.
Seachem Acid Buffer can also be used with Seachem Alkaline Buffer. They are both designed for planted aquariums or those with very hard water. Because they are phosphate free, they will not cause algae or cloudy water.
