Envii Aquarium Chlorine Klear

Removes chlorine and chloramines from tap water when performing regular water changes in fish tanks. Using natural and beneficial Vitamin C, it conditions water and is safe for all fish, wildlife, pets and filtration systems.

Our 100ml bottle, treats 2,500L of water.



Regular water changes in fish tanks help to reduce nitrate levels, remove organic waste and maintain a balanced pH level. However, when adding tap water, you introduce concentrated levels of chlorine and chloramine which can be harmful to fish if not removed with an aquarium dechlorinator.

Removes chlorine and chloramine

Using an aquarium dechlorinator is a simple and quick solution to removing chlorine and chloramine from tap water and therefore making it safe.

Envii Aquarium Chlorine Klear instantly removes chlorine and chloramine from tap water, making it safe to use in your fish tank. We said using a dechlorinator was simple and it really is that simple!

In addition to removing chlorine and chloramines from tap water, aquarium dechlorinators also reduce stress in fish. Stress in fish can commonly occur during water changes and can lead to further illnesses.
