This is one of the most concentrated dechlorinators so a bottle lasts for ages.

What is the Swell Dechlorinator?

The Swell Dechlorinator is designed to condition and treat tap water. It's fish-safe and treats up to 6,056 litres of water. A dechlorinator makes your pond water safe by removing dangerous levels of chlorine and chloramines, that are suitable for humans but not organisms as delicate as the ones in your pond or fish tank. This is one of the strongest dechlorinators on the market, so the bottle represents excellent value for money and treats more than most competiting bottles.

What are the benefits of using a pond dechlorinator?

To make tap water suitable for pond fish, the Swell Dechlorinator removes chlorine, chloramine, and other heavy metals. If these elements are not removed, fish can suffer burns to their gills and to the delicate mucus membrane that protects their skin. This leaves them susceptible to infections and diseases too. Using a dechlorinator efficiently and thoroughly removes these contaminants.
