pH/Alkalinity Down (Decrease) - 1.5lb

Lowering Ph/Alkalinity
If pH is above 7.8 refrain from entering your 
spa and perform the following instructions:
1. For every 500 gallons of spa water add  
½ oz  of HT pH/Alkalinity Down
2. Allow    filtration    pumps    to    run    for    30    minutes,     
retest and repeat Step 1 if necessary.
If pH is in line but Alkalinity is not run all spa 
pumps on high speed for 15 minutes.
For best results dissolve in bucket of spa water 
then pour into spa.
