durby Posted January 9, 2007 Report Share Posted January 9, 2007 Hi I have just had an arctic spa with peak ozone installed. I am using dichlor (Boost) as a sanitizer and find we are having to add 2 - 3 tea spoons a day or the chlorine level drops off the chart. Is this normal with an ozone system reported to reduce chemical demands by 70%? How do I know the peak ozone system is working at all? I know the system is installed but am unsure where I should be seeing the effect in the tub. Suppliers have provided only waffle! Many thanks Quote Link to comment Share on other sites More sharing options...

You need to add enough chlorine to maintain a 4-6 ppm FC level when you enter the spa. IMHO, ozone is miuch more effective with bromne since it actually activates the bromide reserve in the water into active bromine santizer and tends to help keep the bromine levels more constant. While ozone and chlorine can work together it is a bit harder to adjust the levels needed and the chlorine is killed off more quickly. The high temperatures in a hot tub alone can make it difficult to maintain proper free chlorine levels in the water even without ozone. In no circumstances should you ever let your free chlorine readings be below 2 ppm if you want to maintain santized water. Quote Link to comment Share on other sites More sharing options...
Tom Posted January 15, 2007 Report Share Posted January 15, 2007 Hi I have just had an arctic spa with peak ozone installed... How do I know the peak ozone system is working at all? I know the system is installed but am unsure where I should be seeing the effect in the tub. Waterbear has already given a good answer, so I mention only that a Peak Ozone Manual is available for download here. Quote Link to comment Share on other sites More sharing options...
waterbear Posted January 15, 2007 Report Share Posted January 15, 2007 Taylor Technologies makes 2 test kits for ozone, the K-1818 and the K-1822. Both are pricey! (Retail over $100). There really won't tell you much anyway since if your ozonator IS working properly there should be NO residual ozone in the water since ozone is a toxic gas! try turning off the ozone for a week and see if your chlorine demand goes down (in other words, you need less chlorine to maintain a proper free chlorine level in the spa). If it does then your ozone is most likely working properly. Quote Link to comment Share on other sites More sharing options...
