Step 5

Always balance in this order. Alkalinity, PH, Sanitizer.

Step 6

Determine if Alkalinity needs adjustment. (80 ppm – 120 ppm) If so, measure out the correct amount and broadcast over surface of water. If Alkalinity is being adjusted, do not adjust PH at this time. Most often, the PH will naturally rise along with Alkalinity after treatment.

Step 7

Balance the PH (7.2 – 7.6). If Alkalinity is in range, but the PH is out of range, determine the correct amount of increaser or decreaser needed and apply to spa water with pumps running.

Step 8

Wait at least 15 minutes before testing again.

Step 9

Re-test chemicals to be sure Ph is within range

Step 10

Balance Sanitizer. Add needed amount of chlorine or bromine to the water. If using Liquids, never exceed more than ¼ cup at any time. If using granular, never exceed more than 2 tablespoons at a time. You can always add more, but removing sanitizer requires neutralizing chemicals, or non-usage / evaporative times. If using a floater for tablets, add this now.
