This phosphate-free buffer lowers and stabilizes pH in the acid range of 4.0 to 6.8. Designed specifically for freshwater and planted aquariums. May also be used to lower the pH in saltwater aquariums. 300 grams treats approximately 3,000 gallons.

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.

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