The Evolution Aqua Detox Dechlorinator provides professional tap water treatment for koi ponds. Because UK mains water contains chlorine and disinfectants, untreated top-ups can quickly harm fish health. Therefore, treating tap water before it enters your pond is essential.
This inline unit removes harmful chemicals instantly before water reaches your system. As a result, pond owners can perform safe water changes while protecting both koi and beneficial filter bacteria.
Why Tap Water Must Be Treated Before Entering Your Pond
Chlorine and chloramine are added to mains water to kill bacteria. However, these chemicals are highly toxic to koi and biological filtration systems. Consequently, even small amounts can cause serious problems.
If untreated tap water enters a pond, it can:
• Damage delicate gill tissue
• Kill nitrifying bacteria
• Cause fish stress and flashing
• Disrupt ammonia processing
• Reduce long-term water stability
For this reason, a professional dechlorinator should always be used during water changes.
High-Capacity Dechlorination Performance
The Evolution Aqua Detox Dechlorinator 30″ uses specialist filtration media designed to neutralise chlorine efficiently. In addition, the media maintains consistent performance throughout its service life.
Because of its large treatment capacity, this unit is ideal for:
• Routine pond top-ups
• Large water changes
• Quarantine systems
• Drum filter rinse supplies
• Dealer holding systems
Therefore, it is widely used by both hobbyists and professional koi facilities.
Simple Inline Installation
This professional dechlorinator connects directly to a standard hose pipe using supplied fittings. As a result, installation is quick and requires no plumbing modifications.
Once connected, water passes through the media before entering the pond. Consequently, toxins are removed instantly without needing chemical treatments.
