Description
NT Labs GH Minerals Up – General Hardness Booster for Ponds
NT Labs GH Minerals Up is a powder-form water treatment that safely increases the general hardness (GH) of pond water, creating a stable and healthy environment for fish and aquatic life. GH refers to essential minerals like calcium and magnesium that support biological processes such as growth and metabolism in fish. These minerals naturally reduce over time due to rainfall, soft tap water, or biological activity, making regular adjustment necessary.
This 600g container treats up to 1.5kg of water volume and is easy to use – simply dissolve the required amount in a bucket of pond water before adding to the pond. It’s ideal for use alongside NT Labs' GH test kits to maintain consistent water quality.
Key Features:
- FREE standard delivery between Thu 18 Dec - Wed 24 Dec
- £5.95 express delivery between Tue 16 Dec - Wed 17 Dec if you order before 2pm
