Spa Boy® & Onzen™ Saltwater Startup
Before you attempt to balance the water, the water temperature must
first reach a minimum temperature of 85°F (29°C)
Step 1: Establish Correct Water Chemistry
Balancing the water correctly before usage will make the water easier to maintain.Remember
when adding any chemical to have the lid open and run all the pumps to ensure good mixture.
1. Add the initial dose of BEST DEFENCE(2oz/1000L) Run the pumps for a cycle
2. Test & adjust pH. Use the Rainbow Chlorine/Ph test kit provided. pH should be between 7.2 and 7.6
at this stage getting the ph as close to the lower limit will be beneficial as Step 2, adding the salt will
increase ph.
IMPORTANT: Onzen™ requires an additional step using Aquachek yellow test strips to test and
adjust alkalinity before ph. Perfect balance to raise/Adjust down to lower.
Step 2: Mixing & Adding the Salt ** Salt will cause pH to rise
1. Dissolve 1/3 of the required recommended salt dosage in a pail of hot water.
2. Add mixture into the spa with pump(s) running. This will allow the salt to mix thoroughly
throughout the spa.
3. After 30 mins, re-test pH and adjust accordingly if necessary. To lower pH, add 1 cap of salt water
balance. If it goes too low just leave it as pH will rise on its own.
4. Repeat steps 1-3 until all salt has been added.
