Pond GH Conditioner 250g

Phosphate free. Pond Conditioner increases the GH (general hardness) of water to aid osmosis control in fish. It also adds the minerals, elements and trace elements which are often insufficient in tap water and rainwater, but essential for healthy goldfish and koi.

Directions: 1 rounded teaspoon or 8g to 10 litres of water will raise GH by approximately 14dGH or 250ppm and raises pH to over 7.4.
