Out of StockOur shop no longer sells this product.


The Test GH from Söll is a water test for analysing the optimal total hardness in fresh and saltwater aquariums, as well as in the pond.

Water is not simply water. Rainwater already absorbs pollutants and once it seeps into the groundwater, it is enriched with other substances that are not all suitable for the aquarium. Depending on the origin of the water, e.g. due to the nature of the substrate, it may contain different amounts of mineral salts.

Most fish and plants can be successfully maintained with a total hardness of 5-25 ° dH.
