Swimming Pool Muriatic Acid Balancer (14.5% Hydrochloric Acid) - pH and Alkalinity decreaser

Water Balancing - Set up (After Filling the Tub)

This will need to be performed every time you empty and refill the tub.

Step 1: Take the test strip and place it in the water for 2 seconds (directions on test strip tube). Shake once to remove excess water and read immediately.

0-49	Add 3 Tbsp of Calcium Booster
50-99	Add 2 Tbsp of Calcium Booster
100-249	Add 1 Tbsp of Calcium Booster
250-350	No action required
350+	Use an ion exchange filter to strip calcium and hard minerals from the water before filling the tub

Note: The longer you let it sit the more stable the water will become.

Auto Doser Reading Information:

Look at the Auto Doser Controller screen and follow directions below:

Auto Doser pH and ORP reading is fluctuating up.	No action required. Allow the auto doser to stabilize the water.
Auto Doser pH and ORP reading isn’t fluctuating at all and no chemicals can be seen coming through the clear tubing.	Please read the instructions on how to prime the lines of the auto doser in the help center.

Chlorine and pH Management: Routine Testing

Recommended Schedule: Test 1x per day before use.

Min: 7.10 pH

Max: 7.80 pH

Reading	Action
<7.10 pH	Add 1 Tbsp of Spa Up. Retest in 3-5 Hrs
7.11-7.80	No action required
>7.80 pH	Ensure that your pH reservoir is not empty. If below min line, refill reservoir and retest in 3-5 hours. If pH reservoir is above the minimum line: drain some water (3-5 gal) from the tub and add water to the tub as necessary.

Note: If tub exceeds 7.8 pH consistently, please email us at commercial-support@plunge.com.

Step 3: Check the Free Chlorine (FCI)

Recommended Ranges
