Aquarium plants are the green “power stations” of an aquarium. They play several key roles at the same time. Aquarium plants produce oxygen and improve the quality of the water. As a result, aquatic plants help create an appropriate environment for fish. Tetra CompleteSubstrate is perfectly suitable for use when setting up a new aquarium. The optimised mix of quartz encourages plants to take root quickly which in turn activates strong and healthy plant growth. The natural concentrate with long-lasting results is enriched with special micronutrients and minerals.
