The Aqua One WaterSafe & BioStarter Bundle (50ml + 50ml) provides two essential treatments to help create a safe and stable environment when setting up or maintaining an aquarium. By combining a tap water conditioner with a beneficial bacteria starter, this bundle supports both immediate water safety and the development of a healthy biological filtration system.

Aqua One WaterSafe instantly treats tap water by neutralising harmful chemicals such as chlorine and chloramine that can be dangerous to fish. Its anti-stress formula helps protect fish by supporting their natural slime coat, which plays an important role in maintaining overall health and reducing the risk of disease.

Aqua One BioStarter works alongside this by introducing beneficial bacteria into the aquarium filter. These bacteria help establish biological filtration by breaking down harmful ammonia and nitrites produced by fish waste and uneaten food. This process helps maintain balanced water conditions and supports a healthier aquarium environment.

Together, WaterSafe and BioStarter provide a practical solution for new aquarium setups, water changes, and routine maintenance. Using both treatments helps prepare tap water safely while encouraging the rapid establishment of beneficial bacteria within the filtration system.
