Specialized active substrate is made from natural soil, which is subjected to thermal treatment. This process gives the substrate a porous structure and better filtration properties. Compared to other types of substrate, this active one significantly improves water parameters, including those responsible for hardness and pH. By using high-quality active substrate, we obtain slightly acidic water that promotes the proper development of most fish and plants inhabiting the aquarium. The active substrate removes contaminants and discoloration from the water, and also supports the maintenance of nitrifying bacteria. Its purchase is particularly important in the case of aquariums with unique, demanding species of fish and plants, as well as shrimp. Active substrate for shrimp tanks greatly facilitates the breeding of these demanding crustaceans. Water optimization and algae reduction are just some of the tasks that the active substrate designed for shrimp fulfills. Substrate with reduced fertilizer content will ensure the proper development of plants in the shrimp tank, while also positively affecting the aquatic creatures themselves.
