Pond Water Conditioner at AllPondSolutions
A pond water conditioner or dechlorinator is an essential water treatment for any pondkeeper to ensure that their mains water is safe for use in their pond.
A pond water conditioner works by neutralising the chlorine and chloramine present in tap water when filling a pond for the first time or carrying out any water changes. Without the use of a pond dechlorinator, these chemicals can cause upset the balance of the biological bacteria in your pond and poor health in your fish.
Buying guide
When choosing a dechlorinator, dosage matters more than brand: most conditioners are concentrated, so you'll only need a small measured amount per volume of water, making a single bottle last through many top-ups and water changes over a season. Check the dosing instructions against how much water you're actually treating, as overdosing wastes product while underdosing leaves chlorine or chloramine partly neutralised. If you're topping up after a partial water change rather than a full refill, use our pond volume calculator to work out what you need so you're treating the right amount rather than guessing. Keeping a conditioner on hand also means you can respond quickly to unexpected top-ups without leaving your fish exposed to treated mains water in the meantime.
