About the Aquarium Rescue Dechlorinator

Water straight from the tap will attack delicate fish membranes, which is why every water change and every top-up needs conditioning before it reaches the tank. Chlorine control here works in minutes, converting harmful tap water into safe aquarium water.

It removes chlorine compounds and chloramines quickly and safely, and carries additives that stabilise aquarium water and prevent nitrite poisoning, leaving a balanced and healthy fish tank environment. Suitable for use in tropical, marine and coldwater fish tanks, and available in 100ml, 250ml and 500ml.

  • 100ml – Treats 450L (100 gallons)
  • 250ml – Treats 1,136L (250 gallons)
  • 500ml – Treats 2,273L (500 gallons)

Directions:

  • Add 1ml per 4.5 litres (1 gallon) of aquarium water.
