The fascination of freshwater aquariums
Tropical rivers and lakes are home to fascinating animals and plants. Their colours, behaviour and growth forms draw many people to freshwater aquariums.
With hw Wiegandt products, you can adjust water parameters to suit the conditions of natural habitats. Whether you need the very low mineral content of Amazonian waters or the particular conditions of Lake Malawi and Lake Tanganyika, hw water additives and conditioners help you prepare suitable aquarium water.
hw care products for freshwater aquariums
Suitable conditions for thriving aquariums and successful breeding
Aquariums are artificial biotopes with a delicate biological balance. Consistent water quality with low pollutant levels helps maintain this balance. hw Wiegandt care products support water quality and suitable conditions for the animals and plants in your aquarium. We will be happy to help you choose the right product.
Remineralisation of reverse osmosis water and low-mineral freshwater
Freshwater fish and plants often need specific water parameters. Water produced by reverse osmosis or ion exchange may also need to be adjusted before use. Our mineral salt mixes help you establish suitable conditions for your aquarium.
hw ReMineral enriches low-mineral source water, including reverse osmosis and fully demineralised water. It allows you to adjust alkaline-earth mineral content and the associated total hardness (GH), as well as carbonate hardness (KH), to suit your aquarium’s requirements.
hw MineralMarin is a mineral salt mix for reproducing and adjusting the water parameters of Lake Tanganyika and Lake Malawi.
hw specialist filter media for freshwater aquariums
Clear water helps an aquarium look its best, and effective filtration plays an essential part. Filtration must do more than capture suspended particles: it also needs to address dissolved organic and inorganic pollutants. Specially prepared, high-performance activated carbons and other specialist media are designed for these tasks.
For hw filter media, we select high-purity activated carbons together with mineral and semi-synthetic carrier materials. These are treated and combined to target particular pollutants. They complement conventional materials such as filter wool, fleece, foam, clay and ceramics by binding and neutralising dissolved pollutants, colourants and other unwanted substances that conventional media may not adequately remove.
