Keeping the water clean – chemical sanitizers
One of the main reasons that people require service on their spa is because they haven’t followed a proper water sterilization regiment. Water can accumulate impurities that can worsen the performance, or damage the filtration system if chemicals are not properly applied at appropriate intervals. The water can even become unhealthy if chemicals are not used to sanitize the water. Improper pH levels or calcium levels can cause either corrosion of parts or scale build-up.
We recommend that you begin a routine of sterilization that you are comfortable with, and that you can follow through with. If you get into a scheduled regiment, it will be easier to remember when to apply the chemicals or run your alternative system (like Salt, Ozone or UV).
Your spa comes with an ozonator that will do a very good job at killing bacteria and oxygenating the water, but chlorine or bromine are often used to compliment the work of the ozonator.
The best way to keep the water clean over long periods of time is to change the water four times a year. Connect a hose to the drain valve and open it all the way to allow the spa to drain all the way. Use a shopvac to remove any standing water and debris at the bottom of the spa. Refer to the maintenance section for instructions on cleaning the spa before refilling it.
