The hot water in spa pools (בריכות ספא) makes the particlular environment ideal to develop bacterias and micro organisms. To kill such bacterias it is very necessary to use suitable chemical and in certain amount. Spa chemicals are natural, safe and best option to clean spa pools (בריכות ספא).
Some useful Spa Chemicals are :
Bromine acts same as chlorine, but easier to use. Bromine is odourless and is also not irritating to skin andeyes. Bromine is better suited for the high temperatures of the water and is more tolerant of the high pH value and is more stable, too.
EcoONE is a soft spa (בריכות ספא) water treatment you can use to sanitise the water. It does not have any harsh chemicals like chlorine in it. It is made out of natural enzymes, plant extracts and minerals. It naturally and dramatically cleans your spa and the water, nullifying the need to clean it again for the next three months.
If you are not too keen on using spa (בריכות ספא) chemicals for cleaning the water, then you could use a cleaning feature called the ozonator. The ozonator used to make the water cleaner and clearer. It also feels much softer as opposed to after adding chemicals to the water. Ozone is a powerful oxidizing agent that rids the water of the contaminants. These ozone generators for the spa are called ozonators.
