Chemicals

Kasten Masonry offers a full line of spa chemicals. Kasten Masonry offers a chlorine base sanitizing system for spas, or customers could use bromine. Spa water maintenance is very similar to swimming pool maintenance, but their care differs in several ways. Some reasons why spa water care is different than swimming pool is the fact that there is much less water typically to maintain. Two people in a 500 gallon spa have about the same effect on the water chemistry as 80 people in a 20,000 gallon swimming pool.

1. When spa is about half full, add 2 oz. Control. This will control minerals and help prevent staining and scaling, while also clarifying the water.
2. Test the spa water and check the pH. The pH should be maintained between 7.4 and 7.8. If the pH is below 7.4 add pH UP; if above 7.8 add pH DOWN. Test alkalinity and adjust if necessary.
3. When starting the Bromine Tablet system put tablets in appropriate feeder. Let spa circulate until a bromine reading of 3-5 PPM is attained. You may need to adjust feeder to keep the 3-5 PPM level consistent.
   

1. When spa is about half full, add 1 oz Spa Bright. This will control the minerals and help prevent staining and scaling, while also clarifying the water.
2. Turn spa on when it is full with water.
3. Add one tablespoon of Sani Spa to super shock the water and to establish a chlorine residual.
4. At this time, test the water. Check the pH and maintain between 7.4 and 7.8. If the pH is below 7.4 add pH UP, if it is above 7.8 add pH DOWN.

Add 1 teaspoon Sani Spa after each day of use. By doing so, you will destroy the organic contamination build up. When the sanitizer is consistently maintained at 3 – 5 PPM and the pH at 7.5 the water will be sanitary and safe for use.
