The benefits of eco3spa over chlorine

There is a wealth of evidence that chlorine is harmful to health. For example, the United States Agency for Toxic Substances & Disease Registry (ATSDR) has published data that shows that the following effects have been observed in humans briefly exposed to chlorine (Nov 2010 Cas#:7782-5-5) : - mild nose irritation at 1-3ppm - eye irritation at 5ppm - throat irritation at 5-15ppm - immediate chest pain, vomiting, changes in breathing rate and cough at 30ppm - lung injury (toxic pneumonitis) and pulmonary oedema (fluid in the lungs) at 40-60ppm - death after 30 minute exposure at 430ppm - death after a few minutes exposure to 1,000ppm The concentrations listed above are approximate. In general, people who suffer from respiratory conditions, such as allergies or hay fever, or who are heavy smokers tend to experience more severe chlorine exposure effects than healthy people or non-smokers. Manufacturers of hot tub chlorine recommend a dosage of 5ppm of chlorine in your hot tub during daily use and significantly higher levels for regular shocking. There is overwhelming evidence that these levels of chlorine exposure are harmful to your body.

Very few! Both chlorine and bromine's biocidal abilities are severely hindered by water hardness and poor pH control, but bromine slightly less so. Both chlorine and bromine react with organic contaminants and this reaction leads to the formation of potentially toxic disinfection-by-products such as trihalomethanes, halomethanes, haloacetic acids and chloramines. It is these bi-products that cause smell and skin irritation and well as toxicity. There are arguably less undesirable bi-products of the sanitation process when bromine is used, but the process is still extremely toxic. The only slight benefit is that bromine remains more stable at higher temperatures than chlorine does. Active Oxygen has none of these undesirable properties.

There are so many reasons.... Chlorine causes skin irritation; chlorine smells of chlorine!; chlorine requires constant pH balancing for it to work safely; chlorine bleaches swimwear; chlorine is toxic to plants and animals........

Adding chlorine to hot or cold tub water is not straightforward. You need to get the Total Alkalinity, pH and Calcium Hardness levels in your water just right before you add any chlorine (this process is otherwise known as 'balancing'). If you don't balance the water the chlorine becomes ineffective and won't kill all the bacteria. Just the process of adding chlorine granules or tablets to the water will alter the water pH value so you need to constantly test and adjust the water's balance. It can be a never ending loop! In contrast eco3spa has been shown to be effective over an extremely wide pH range and independent research has demonstrated that the sanitising effectiveness of eco3spa is virtually unchanged between pH 5.6 and pH 8.5. What's more, the eco3spa Step 2 Water Conditioner contains a pH stabiliser so, if you do need to adjust the pH of the water in the tub because your source water has a very high pH (ie it is extremely hard), you only need to do it once when you fill your tub. Thereafter you don't need to worry about pH again until your next water change.
