Kusuri – Dechlorinator

Code: MD920, MD921, MD922, MD923

Kusuri Dechlorinator is a tap water conditioner designed to remove chlorine during pond water changes and top-ups. It helps protect koi and supports healthy biological filtration when adding mains water to your pond.

Price range: £10.95 through £58.95

Product Description

Adding tap water straight into your pond introduces chlorine that can harm fish and damage your biological filter. Kusuri Dechlorinator is formulated to remove chlorine from tap water, making it safe to use during water changes and top-ups.

If you carry out regular maintenance or automatic trickle-in water changes, a reliable dechlorinator is essential.

Why use Kusuri Dechlorinator?

  • Removes chlorine from tap water
  • Protects fish during water changes
  • Helps safeguard biological filtration
  • Suitable for routine pond top-ups

Chlorine is added to mains water for safety, but even small amounts can irritate gills and disrupt beneficial filter bacteria. Treating water before or during addition helps prevent unnecessary stress.

When to use

  • During partial water changes
  • When topping up after evaporation
  • After heavy backwashing or filter cleaning

Always calculate your pond volume and the amount of new water being added before dosing.

Good practice & safety

  • Dose according to the manufacturer’s instructions.
  • Add to incoming water where possible for even distribution.
  • Store in a cool, dry place.
  • Keep out of reach of children and pets.

Kusuri Dechlorinator is a simple but essential part of pond maintenance, helping you carry out water changes confidently while keeping koi safe.
