Adding Water
Dependign on how hydro- phillic or hydro- phobic the water is, the water can evaporate faster. Certain water can cause more condensation than others on the lid of the float spa. I prefer spas that do not evaporate as fast especially when the evaporated water is full of expelled toxins from the body. Many people sweat and this can add up to gallons of sweat and urea. It is a burden to keep adding water from containers to keep the level up. The better ones have automatic watering systems so you don't have to manually do it.
Some people put distilled in the water and soem people put filtered tap water. If some people put restructuring devices or are charging the water prior to each use, it can clump the minerals in the salts and heavy metals which make it hard to purifiy even with the best filtration systems. If using an RO system I would definately restructure the water.
Some system circulate water more cycles per session than others. But, you want to be concerned about EMF and wattage as you don't want the person to be exposed to too high of these frequencies. Some tubs have the electrical components shielded which are the ones that I prefer to use but I always carry in an EMF blocker on my neck all the time regardless of where I am going. I won't even sit in a coffee shop or an internet cafe due to Wifi. I even bring my emf sensor and will not sit near certain walls in the coffee shops.
Remember, it does not matter how good the water system is if the filtered water is unstructred and hydro-phobic.
Take the float quiz if you want help choosing the right float spa.
