100% NATURAL. Every owner of underwater pets knows that decorations and aquarium substrates not only look nice, but also affect the environment of our fish. That is why it should be ensured that most of them are natural. Not artificially coloured and looks natural.
Some of the used sands have very little influence on the chemical values of water. It is therefore advisable to use such materials for the substrate of Tanganyika aquarium which would have a high content of magnesium reacting with our water. Such rocks include DOLOMITES.Metasomatic dolomites were formed in the process of metasomatic transformation of limestone (calcite) deposits. In this process, the calcium carbonate they contained was partially displaced by magnesium carbonate. The source of magnesium in these transformations was sea water.
Before use, we recommend that you only pre-wash the substrate, please do not do this thoroughly because it is a never-ending work. After pouring out the substrate into the aquarium and covering it with water, a natural cloudiness may occur, which will disappear very quickly after starting the filtration.
Please note that the total weigh of a bags may vary +/- 2%
