Tetra FilterActive contains living starter bacteria which settle within the filter in your aquarium and work to break down nitrite and ammonia, which are harmful to fish, to maintain a healthy biological balance.

This formula also contains sludge-reducing, cleaning bacteria which help to keep the filter cleaner for longer by accelerating the biological decomposition of pollutants and waste. This helps improve the performance of your filter and keep it cleaner for longer.
