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.
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.

I’ve used Gold Buffer for over six months and my goldfish have stayed healthy. The pH has remained stable between 7.4 and 7.6. No algae issues either. Easy to measure and mix. Works well even in a soft water setup.
Anne Hunter –
Good product for maintaining stable pH. I use half the dose since my tank water is soft. It takes a few days to see the effect, but once it starts working, the pH stays consistent.
Wendy Peake –
My goldfish were showing signs of stress due to fluctuating pH. After adding Gold Buffer, the water stabilized. I haven’t had any algae growth, which is a bonus. Very reliable.
