Aqua-Pics Amazon KH Buffer 800g
Amazon KH Buffer helps your aquarium water emulate the waters of the Amazon Basin by raising KH (carbonate hardness) without compromising the slightly acidic pH required for fish that come from this region, such as discus, tetras, Apistogramma and L-number catfish. It raises KH and locks in pH to approximately 6.5 to 6.8, stopping pH fluctuation, creating pH stability and reducing stress on fish. Contains chemically clean phosphates, which should not exacerbate algae.
Directions: 1 level teaspoon to 8 litres of water will raise KH by approximately 6dKH or 107ppm and stabilise pH to around 6.5 to 6.8.

James Black –
Used this buffer in my discus tank for three months. The pH stayed steady between 6.6 and 6.7, and my fish showed no signs of stress. Water clarity improved and I didn’t notice any algae issues. Easy to measure and effective.
Deirdre Lee –
Good for maintaining stable pH in a tetra tank. Added once a week after water changes. KH levels increased as expected and fish seem more active. A reliable product for Amazonian fish.
Melanie Ross –
My Apistogramma fish have been thriving since I started using this buffer. The pH remains stable and the water feels more balanced. No algae growth, and the instructions are clear and simple.
