Because a large number of plants and animals live together in a relatively confined space in an aquarium, much greater demands are placed on the water than in the natural environment. An aquarium cannot maintain its biological equilibrium by itself. amtra was the first aquarium supplies producer to come up with a natural solution: amtra clean. The original. It supports the self-cleaning process of the water by means of naturally occurring micro-organisms which neutralise the harmful substances resulting from residual food and excretion products. This prevents the water from becoming contaminated, protects the filter material and saves up to 50% of water changes. amtra clean turns your aquarium into a healthy, biologically intact environment for healthy fishes and plants.
