Using traditional chemical methods to stabilize the water is complicated and time consuming to say the least. Water chemistry must be understood and the fundamentals are described next. When using traditional chemicals, we recommend that you check your water quality daily.
In a manually controlled system, the target levels for spas are:
-
Bromine: 3.0 - 5.0 ppm
-
pH: 7.6 - 8.2
-
Total Alkalinity: 80 - 120 ppm
-
Calcium Hardness: 200 - 400 ppm (also known as Total Hardness)
-
Total Dissolved Solids: 1,500 ppm above your start-up Total Dissolved Solids
The easiest way to test for these levels is to use commercially available test strips. Many companies offer them but once opened their accuracy deteriorates with time. For this reason, buy small quantities to get the most accurate readings. Follow the directions with your test-strip product and write down the levels of each.
Note: When using the legacy bromine water management the filtration cycle should be set to "02"
