Microbe-Lift Special Blend helps to break down decaying organic matter and cycle elements like nitrogen and sulfur to prevent them from building up in your aquarium. This formula will reduce water changes and cleaning maintenance with chemical free ingredients, by lowering ammonia levels and nitrates while removing odors, clarifying water and breaking down protein foam as well as residue on gravel, plants and rocks. As this Special Blend sustains your aquarium water, plant growth is naturally stimulated while light, water and nutrients are better absorbed into plants for freshwater and saltwater aquariums. This biological maintainer is suitable to use as an aquarium starter for biological cycling and boosting. Activated carbon and copper based products are compatible with this formula.
