Söll GH-Plus, 500 ml

To ensure that fish and plants thrive in your pond, they require a consistent supply of essential calcium. Because this macronutrient is continually depleted by the pond's natural biological processes, you can use GH-Plus from Söll to boost the total hardness (GH) quickly and effectively.

By maintaining proper levels, you ensure that beneficial microflora remains active and that your aquatic plants can efficiently absorb essential nutrients. Whenever levels drop below the critical 5 °dH mark, this product restores the biological balance to the ideal range of 10 to 15 °dH, all without affecting the carbonate hardness (KH).

Application & Dosage:

• Use GH-Plus whenever the total hardness falls below 5 °dH.
• Pre-mix the required amount in a bucket with approximately 10 litres of pond water and distribute the solution evenly across the surface.
• A dosage of 50 ml of GH-Plus per 1,000 litres of pond water will increase the total hardness by 1 °dH.
