• How does ChlorDown cut chlorine use?

    The unique ionic composition of ChlorDown boosts the efficacy of free chlorine in your pool or spa meaning less chlorine is needed to operate safely and effectively.  


    Peer reviewed studies show the ions used in ChlorDown increase chlorine efficacy against the bacteria and viruses found in pools and spas as well as making the chlorine biocide residual more stable.

  • Can ChlorDown save us money?

    Yes it can!  When you add ChlorDown the unique formula means you can reduce your chlorine set point down to as low as 0.5ppm with ease thus slashing your chlorine consumption.

  • What are DBPs and how does ChlorDown reduce them?

    With ChlorDown in your pool less chorine is added so less of the dangerous disinfectant byproducts such as chloroform and other trihalomethanes are produced as bathers swim.  This in turn improves both the air and water quality.


    Trihalomethanes have been reduced by as much as 150% in published pool field trials of the ions found in ChlorDown combined with free chlorine.  With new DBP limits for pools being introduced, ChlorDown is a cost effective way for pool operators to mitigate the impact of halogen biocides on their water and air quality.

  • Can we use ChlorDown with our current dosing system?

    Of course.  Your chlorine dosing system remains exactly as is dosing your chlorine, albeit at a lower set point, and controllig your pH.  Safe to handle and easily dosed via a simple continuous feed system, adding ChlorDown is an quick and simple task.  


    This is achieved with a small continuous feed automated doser in the plant room via an extra injector point post filter, UV and heat exchanger on the pool return a suitable distance from the chlorine injector. 


    All your pool operational procedures such as backwashing frequncy remain the same and water balance does not need to alter.

  • Can ChlorDown be used in outdoor spas and pools?

    Definitely!  Thanks to ChlorDown's unique ionic profile it is far more stable in outside pools than chlorine as ChlorDown is not destoyed by UV light.  Furthermore thanks to the ions you will not only use less chlorine but less algacide too. 

  • How much is the ChlorDown system?

    The complete conversion pack for one pool contains a dosing system with 13A plug, pump and isolator mounted on a 600mm square board  plus 10m of dosing line and sheathing, an injector, photometric tester kit, test strips, access to our online and live training and 5L of ChlorDown (enough to convert a 250,000L pool) is only £1,250 plus UK delivery.  We can install this and provide onsite personalised training for an additional £245 plus travel.  Alternatively your own pool contractor can install the ChlorDown system for you

  • We've got UV - does that matter?

    Not at all, you can keep your UV running if you want.  Many suppliers of UV claim their systems can run with only 0.5ppm of chlorine but you've probably found now that is generally not the case, esepcuially if you have a busy pool.  The benefit of ChlorDown is that you really will be able to run at a much lower level of chlorine that you are using now even with your UV system.
