Marine KH Buffer Phosphate free 1kg

Phosphate free. As marine life needs a stable environment, our Marine KH Buffer raises carbonate hardness, locking the pH at around 8.4pH. It also helps to maintain high alkalinity, stopping pH fluctuations, creating pH stability and reducing stress on fish and corals. Add 1 heaped teaspoon to 20 litres of water to raise carbonate hardness by approximately 9dKH (160ppm).
