Never fill the spa with softened water unless an appropriate mineral supplement is immediately added. If your water is extremely hard, seek advice on balancing the water before use. For assistance, contact info@spaswholesale.com.au.
Step 1: Fill the spa and use suitable spa water-care products according to their current label directions.
Step 2: Test calcium hardness and adjust it to the range recommended for your spa and water-care products.
Step 3: Test and adjust Total Alkalinity (TA). Follow the chemical manufacturer's current instructions.
Step 4: Test and adjust pH. A commonly recommended spa range is approximately 7.2–7.6; always follow the directions for the water-care system you are using.
Step 5: Sanitise the water using a spa-approved sanitiser and follow the product label for correct dosing. Never mix incompatible chemicals and do not exceed the manufacturer's directions.
Step 6: Allow the filtration system to circulate the water and re-test before use.
Correct water balance helps protect spa equipment and keeps the water comfortable. Use spa water test strips or an appropriate test kit and maintain the chemistry within the ranges specified by your water-care product manufacturer and spa documentation.
