Oase Inline Dechlorinator

Pond water testing support for safer treatment decisions

Oase Inline Dechlorinator is a powerful, easy-to-use solution for ensuring that tap water is safe for your pond, aquarium, and all aquatic life. While tap water is safe for humans, it often contains chlorine, chloramine, and heavy metals that can be harmful or even fatal to sensitive fish, plants, and beneficial filter bacteria. Using a high-performance activated carbon cartridge, the Oase Inline Dechlorinator immediately binds and removes chlorine, chloramine, and heavy metals from the water during the filling process.

Simply connect the unit between your outside tap and garden hose using the high-quality metal quick-release couplings provided, and you can safely fill or top-up your pond or aquarium without delay. Compact and highly efficient, the dechlorinator measures just 505mm in length and can treat up to 200,000 litres of tap water before replacement is required.

It operates best with a maximum recommended flow rate of 500 litres per hour (around.

Water testing products are the starting point for most pond treatment decisions. Accurate test results help show whether the issue is ammonia, nitrite, pH, KH, phosphate, chlorine, nitrate or another water parameter. This avoids guessing, reduces unnecessary dosing and gives a clearer record of how the pond responds after treatment, water changes or filter maintenance.

Oase water treatment and testing products are designed for diagnosis, water improvement and larger pond/lake applications. Water analysis should come before dosing wherever fish behaviour or water quality is uncertain.
