Tetra AlgoStop Depot 12 tablets – aquarium algae treatment for freshwater aquaria, slow-release depot tablets

Tetra AlgoStop Depot is a set of 12 slow-release depot tablets formulated to treat and control common algae in freshwater aquaria. Designed for targeted application, each tablet dissolves gradually to deliver active ingredients directly where algae growth occurs, allowing treatment without noticeably affecting water clarity. The product is intended for routine maintenance and spot treatment in both planted and fish-only freshwater tanks when used according to the instructions on the packaging.

Advantages

The slow-release depot design ensures a prolonged local effect on algae while minimizing widespread dispersal of active substances through the entire aquarium. Tablets are compact and simple to place in the affected area, enabling targeted action on surfaces and hard-to-reach spots. The formulation is suitable for use in planted tanks and fish-only aquaria when dosing guidelines are respected, providing an effective balance between algae control and aquarium ecosystem stability.

Suitable for

• Treating localized green spot algae on glass, rocks and hardscape
