Seachem Gold Buffer

Gold Buffer™ is a non–phosphate buffer that will maintain the ideal pH for goldfish while not enhancing algae growth. Depending on dosage, Gold Buffer™ raises pH and buffers between 7.2 and 7.8. It is gentle, safe, and enhances the freshwater environment. Contains sodium, potassium, magnesium, and other bicarbonate salts. 

Directions

DIRECTIONS: Use 1 level teaspoon for every 40 L (10 US gallons) daily until desired pH is reached. If water is soft or not well buffered, use half dose. Gold Buffer™ will slowly raise pH. It will not lower pH. It may be added directly to the aquarium at any time. It preferentially buffers at pH 7.8, but can manage any pH between 7.2 and 7.8.
