Some Alternative Hot Tub Sanitizers
Some people who have extra sensitive skin may have chances of getting allergic reactions (due to bromine or chlorine). And this kind of experience should be avoided, and the other alternatives should be your choice.
This sanitizer type makes use of the radiation of UV bulbs of high-intensity for eliminating bacteria or germs. Though you may require an extra sanitizer with it to maintain water clarity.
Hence, go for UV systems that can be used in combination with the other systems like chlorine, bromine, or intermittent shocks.
This is another natural way that helps in killing contaminants. The ionization process leads to releasing of silver and copper ions inside the water.
Similar to the UV system this is dependent on shocks for maintaining an absolute sanitary environment. Just go with the shelf-life of ionizers and replace as and when required.
Their usage will depend on the contaminant amount in the water.
