Remember to keep it simple. There are many resources here. Your main concern is to
make sure you don't have phosphates in your water. Phosphates are a nutrient for algae,
consume your sanitizer and cause chlorine production issues with salt water chlorine
generation. You must make sure all phosphates are removed from the water before using.
It is recommended that the SPA owner check chlorine and pH levels before each use or once weekly if not in use. Total Alkalinity, Calcium Hardness, and Salt PPM should be checked at least once per month.
It is recommended that the SPA be shocked once per month, or bi-weekly if used more frequently.
Notes for SPA’s with metal components: Chlorine levels above 5.0 ppm or salt concentrations above 5000 ppm may lead to corrosion of metal components.
It is important to measure the total alkalinity of your SPA regularly. Ideally, you should keep a hot tub between 100-150 alkalinity. If your pH is a little high, you can add a little white vinegar to lower it. The TechniChlor & ColorChlor will raise the pH in a couple of days. If your pH is extremely low (less than 7.0), add a few tablespoons of common baking soda. Always remember to leave the tub circulating for a couple of hours before retesting.
