AlgoStop depot from Tetra ensures a long-term algae-free aquarium and is ideally suited for all tanks from 40 l upwards. Due to the depot formula, the highly concentrated active ingredient is released slowly over a period of approx. four weeks and ensures long-term prevention of algae growth.
When used properly, AlgoStop depot is harmless to all aquarium inhabitants, plants and microorganisms. Please follow the manufacturer's instructions for use. The highly concentrated active ingredient actively intervenes in the metabolism of the algae and effectively prevents their formation. The aquarium water is not discoloured during application. It is recommended to aerate the aquarium with a pump during the use of AlgoStop depot in order to ensure a sufficient oxygen supply. In order not to further disturb the balance in the aquarium, it is advisable to remove dead algae mechanically, e.g. with a net. Tetra AlgoStop depot is suitable for all freshwater aquariums.


  • Slow release of the active ingredient over approx. 4 weeks
  • Compatible with all aquarium inhabitants, plants and micro-organisms when used correctly.
  • There are 12 depot tablets in each pack
  • For all freshwater aquariums


Add 1 tablet of Tetra AlgoStop depot to 40 l of aquarium water. Repeat after 4 weeks if necessary. Detailed product information inside.

Instructions for use

During application, aeration of the aquarium by an aquarium air pump is necessary to ensure sufficient oxygen supply. Dead algae should preferably be removed mechanically with a net, as they have a negative effect on the water quality.
