Six Steps to Starting Up a Master Spa

Six Steps to Starting Up a Master Spa

Step 1: Fill your Master spa with hard water.

Never use more than 50% softened water to fill up your spa, and consider using a pre-filter—it’ll make it much easier to adjust your water balance!

Step 2: During the initial fill, add SpaBoss Prevent II (or another sequestering agent).

This will eliminate staining and scaling caused by dissolved metals and minerals in the water. Let the water circulate and filter until its temperature reaches 80 degrees before adding any other chemicals.

Step 3: Check the hardness levels.

The ideal range is between 150-250 PPM (parts per million). If you are not within range, add SpaBoss Cal-Rise to increase the hardness level.

Step 4: Check the alkalinity levels.

The total alkalinity should be between 80-150 PPM. Add SpaBoss pH Minus to lower the level, or SpaBoss Alka-Rise to increase the level.

Step 5: Test the pH levels.

The pH should fall between 7.2-7.8 PPM. If the pH is low, add SpaBoss pH Plus. If the pH is high, add SpaBoss pH Minus. (Note: If you use SpaBoss pH Minus, it will also lower your alkalinity, so be sure to re-check alkalinity levels after you use it.)

Step 6: After all other levels are properly adjusted, add SpaBoss Chlor-Aid to sanitize the water.

Master Spa recommends adding 2 tbsp. of per 500 gallons. Do not enter the spa until your chlorine levels are below 5 PM.
