This bioBoost sachet helps to activate your filter media, and improves performance by accelerating filtration bacteria, which in turn helps to promote the vitality of any inhabitants, including fish and plants.

This sachet contains more than 1 billion filter bacteria, and is ideal for aquariums up to 500l, and can be used in any type of filter. These will last for around 4 weeks, and can then be replaced as needed, especially whenever your filter needs a special boost, such as around large water changes or large changes in the tanks, or when fish are added.
