The Oase AquaActiv Inline Dechlorinator is essential for ensuring the health and safety of your pond's inhabitants. Tap water, while safe for humans, can contain harmful chlorine, chloramine, and heavy metals that are detrimental or even fatal to sensitive fish, plants, and other aquatic life. This dechlorinator effectively removes these harmful additives using high-performance active carbon, making replenished tap water safe for your pond ecosystem. It is designed for simple installation, easily connecting to standard garden hosepipes with high-quality metal quick-release couplings. This allows for straightforward connection to an outside tap, providing you with peace of mind that the water you add to your pond is clean and safe.
