What is the GH value?
The GH value (general hardness) indicates the amount of minerals—particularly calcium and magnesium—dissolved in the pond water. These minerals are essential for a healthy biological balance in the pond, the growth of aquatic plants, and the health of fish. A GH value that is too low can lead to problems such as reduced plant growth and a less stable pond environment.
Why use GH Plus?
When the GH value falls below the recommended level (usually between approximately 8° and 12° dH), supplementation is necessary. Rainwater, decalcified tap water, or frequent water changes can lower the GH value. With GH Plus, you can add minerals in a controlled manner to restore and maintain your pond water's balance. Because both GH-Plus and KH-Plus affect water chemistry—and the balance between them is crucial—using both products together is not recommended. We recommend a waiting period between uses to prevent unexpected chemical reactions or overcorrection.
Who is GH Plus suitable for?
GH Plus is ideal for ornamental ponds, koi ponds, or swimming ponds that are home to valuable fish and plants. Whether you've just installed your pond or have been maintaining it for years, maintaining your GH level remains important for a healthy aquatic environment.
Usage & tips
First, measure the GH value of your pond with a test kit or drip test. If the value is below the norm, add GH Plus according to the dosage on the package. Check the GH value regularly, for example, after heavy rainfall or water changes, to avoid surprises. Combine GH Plus with good filtration, aeration, and plant care for optimal results.
